a = 6378137.0 metre
1/f = 298.2572236
then e = 0.081819191
Latitude of natural origin (latO): 90°00'00.000"N =1.570796327 rad
Longitude of origin (longO): 0°00'00.000"E=0.0 rad
Scale factor at natural origin (ko): 0.994
False easting (FE) 2000000.00 metre
False northing (FN) 2000000.00 metre
Forward calculation for:
Latitude (lat) =73°N =1.274090354 rad
Longitude (lon) =44°E =0.767944871 rad
t = 0.150412808
rho = 1900814.564
whence
E = 3320416.75 m
N = 632668.43 m
Reverse calculation for the same Easting and Northing (3320416.75 E, 632668.43 N) first gives:
rho' = 1900814.566
t' = 0.150412808
chi = 1.2722090
Then
Latitude (lat) = 73°00'00.000"N
Longitude (lon) = 44°00'00.000"E

Latitude of natural origin must be either 90 degrees or -90 degrees (or equivalent in alternative angle unit).
Note: These formulas have been transcribed from EPSG Guidance Note #7-2. Users are encouraged to use that document rather than the text which follows as reference because limitations in the transcription will be avoided.
For the forward conversion from latitude and longitude, for the south pole case
E = FE + rho * sin(lon ? lonO)
N = FN + rho * cos(lon ? lonO)
where
t = tan(pi/4 + lat/2) / {[(1 + e sin(lat)) / (1 ? e sin(lat))]^(e/2)}
rho = 2*a*ko*t / {[(1+e)^(1+e) (1?e)^(1?e)]^0.5}
For the north pole case,
rho and E are found as for the south pole case but
t = tan(pi/4 ? lat/2) * {[(1 + e sin(lat)) / (1 ? e sin(lat))]^(e/2)}
N = FN ? rho * cos(lon ? lonO)
For the reverse conversion from easting and northing to latitude and longitude,
lat = chi + (e^2/2 + 5e^4/24 + e^6/12 + 13e^8/360) sin(2 chi)
+ (7e^4/48 + 29e^6/240 + 811e^8/11520) sin(4 chi)
+ (7e^6/120 + 81e^8/1120) sin(6 chi) + (4279e^8/161280) sin(8 chi)
where rho' = [(E-FE)^2 + (N ? FN)^2]^0.5
t' =rho' {[(1+e)^(1+e) * (1? e)^(1-e)]^0.5} / (2 a ko)
and for the south pole case
chi = 2 atan(t' ) ? pi/2
but for the north pole case
chi = pi/2 - 2 atan t'
Then for for both north and south cases if E = FE, lon = lonO
else for the south pole case
lon = lonO + atan2[(E ? FE),(N ? FN)]
and for the north pole case
lon = lonO + atan2[(E ? FE),(FN ? N)]

Since the natural origin may be at or near the centre of the projection and under normal coordinate circumstances would thus give rise to negative coordinates over parts of the mapped area, this origin is usually given false coordinates which are large enough to avoid this inconvenience. The False Easting, FE, is the value assigned to the abscissa (east or west) axis of the projection grid at the natural origin.
