Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051920, here are decompositions:

7 + 1051913 = 1051920
17 + 1051903 = 1051920
31 + 1051889 = 1051920
41 + 1051879 = 1051920
71 + 1051849 = 1051920
73 + 1051847 = 1051920
101 + 1051819 = 1051920
109 + 1051811 = 1051920

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 5, 1920 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1920-05-01 (DMMYYYY (Euro, single-digit day))
1920-10-05 (MMDYYYY (US, single-digit day))
1920-05-10 (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 1,051,920 and was likely granted around 1912.

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