Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041890, here are decompositions:

37 + 1041853 = 1041890
61 + 1041829 = 1041890
67 + 1041823 = 1041890
97 + 1041793 = 1041890
103 + 1041787 = 1041890
271 + 1041619 = 1041890
307 + 1041583 = 1041890
313 + 1041577 = 1041890

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 1890 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1890-04-01 (DMMYYYY (Euro, single-digit day))
1890-10-04 (MMDYYYY (US, single-digit day))
1890-04-10 (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 1,041,890 and was likely granted around 1912.

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