Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021750, here are decompositions:

3 + 1021747 = 1021750
53 + 1021697 = 1021750
89 + 1021661 = 1021750
173 + 1021577 = 1021750
179 + 1021571 = 1021750
263 + 1021487 = 1021750
293 + 1021457 = 1021750
347 + 1021403 = 1021750

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 1750 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1750-02-01 (DMMYYYY (Euro, single-digit day))
1750-10-02 (MMDYYYY (US, single-digit day))
1750-02-10 (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 1,021,750 and was likely granted around 1912.

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