Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012500, here are decompositions:

11 + 1012489 = 1012500
19 + 1012481 = 1012500
37 + 1012463 = 1012500
43 + 1012457 = 1012500
53 + 1012447 = 1012500
61 + 1012439 = 1012500
67 + 1012433 = 1012500
79 + 1012421 = 1012500

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 2500 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

2500-10-01 (MMDYYYY (US, single-digit day))
2500-01-10 (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 1,012,500 and was likely granted around 1911.

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