Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012810, here are decompositions:

41 + 1012769 = 1012810
47 + 1012763 = 1012810
59 + 1012751 = 1012810
89 + 1012721 = 1012810
107 + 1012703 = 1012810
131 + 1012679 = 1012810
173 + 1012637 = 1012810
179 + 1012631 = 1012810

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 2810 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

2810-10-01 (MMDYYYY (US, single-digit day))
2810-01-10 (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 1,012,810 and was likely granted around 1911.

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