Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041920, here are decompositions:

13 + 1041907 = 1041920
31 + 1041889 = 1041920
67 + 1041853 = 1041920
79 + 1041841 = 1041920
97 + 1041823 = 1041920
127 + 1041793 = 1041920
163 + 1041757 = 1041920
277 + 1041643 = 1041920

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 1920 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1920-04-01 (DMMYYYY (Euro, single-digit day))
1920-10-04 (MMDYYYY (US, single-digit day))
1920-04-10 (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 1,041,920 and was likely granted around 1912.

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