Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042810, here are decompositions:

11 + 1042799 = 1042810
29 + 1042781 = 1042810
101 + 1042709 = 1042810
107 + 1042703 = 1042810
179 + 1042631 = 1042810
191 + 1042619 = 1042810
227 + 1042583 = 1042810
233 + 1042577 = 1042810

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 2810 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2810-04-01 (DMMYYYY (Euro, single-digit day))
2810-10-04 (MMDYYYY (US, single-digit day))
2810-04-10 (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 1,042,810 and was likely granted around 1912.

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