Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031810, here are decompositions:

79 + 1031731 = 1031810
103 + 1031707 = 1031810
181 + 1031629 = 1031810
277 + 1031533 = 1031810
331 + 1031479 = 1031810
349 + 1031461 = 1031810
379 + 1031431 = 1031810
397 + 1031413 = 1031810

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 1810 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1810-03-01 (DMMYYYY (Euro, single-digit day))
1810-10-03 (MMDYYYY (US, single-digit day))
1810-03-10 (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 1,031,810 and was likely granted around 1912.

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