Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051940, here are decompositions:

13 + 1051927 = 1051940
37 + 1051903 = 1051940
61 + 1051879 = 1051940
151 + 1051789 = 1051940
181 + 1051759 = 1051940
193 + 1051747 = 1051940
223 + 1051717 = 1051940
277 + 1051663 = 1051940

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 1940 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1940-05-01 (DMMYYYY (Euro, single-digit day))
1940-10-05 (MMDYYYY (US, single-digit day))
1940-05-10 (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 1,051,940 and was likely granted around 1912.

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