Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051900, here are decompositions:

11 + 1051889 = 1051900
53 + 1051847 = 1051900
71 + 1051829 = 1051900
89 + 1051811 = 1051900
137 + 1051763 = 1051900
191 + 1051709 = 1051900
251 + 1051649 = 1051900
257 + 1051643 = 1051900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 1900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1900-05-01 (DMMYYYY (Euro, single-digit day))
1900-10-05 (MMDYYYY (US, single-digit day))
1900-05-10 (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 1,051,900 and was likely granted around 1912.

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