Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051810, here are decompositions:

29 + 1051781 = 1051810
47 + 1051763 = 1051810
101 + 1051709 = 1051810
113 + 1051697 = 1051810
167 + 1051643 = 1051810
191 + 1051619 = 1051810
239 + 1051571 = 1051810
251 + 1051559 = 1051810

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 1810 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1810-05-01 (DMMYYYY (Euro, single-digit day))
1810-10-05 (MMDYYYY (US, single-digit day))
1810-05-10 (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 1,051,810 and was likely granted around 1912.

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