Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021252, here are decompositions:

53 + 1021199 = 1021252
179 + 1021073 = 1021252
233 + 1021019 = 1021252
251 + 1021001 = 1021252
263 + 1020989 = 1021252
293 + 1020959 = 1021252
359 + 1020893 = 1021252
431 + 1020821 = 1021252

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 1252 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1252-02-01 (DMMYYYY (Euro, single-digit day))
1252-10-02 (MMDYYYY (US, single-digit day))
1252-02-10 (DDMYYYY (Euro, single-digit month))

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,021,252 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
