Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051918, here are decompositions:

5 + 1051913 = 1051918
29 + 1051889 = 1051918
71 + 1051847 = 1051918
89 + 1051829 = 1051918
107 + 1051811 = 1051918
137 + 1051781 = 1051918
269 + 1051649 = 1051918
311 + 1051607 = 1051918

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 5, 1918 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1918-05-01 (DMMYYYY (Euro, single-digit day))
1918-10-05 (MMDYYYY (US, single-digit day))
1918-05-10 (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 1,051,918 and was likely granted around 1912.

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