Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041878, here are decompositions:

37 + 1041841 = 1041878
307 + 1041571 = 1041878
349 + 1041529 = 1041878
367 + 1041511 = 1041878
457 + 1041421 = 1041878
571 + 1041307 = 1041878
709 + 1041169 = 1041878
727 + 1041151 = 1041878

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 1878 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1878-04-01 (DMMYYYY (Euro, single-digit day))
1878-10-04 (MMDYYYY (US, single-digit day))
1878-04-10 (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 1,041,878 and was likely granted around 1912.

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