Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051640, here are decompositions:

19 + 1051621 = 1051640
97 + 1051543 = 1051640
181 + 1051459 = 1051640
223 + 1051417 = 1051640
307 + 1051333 = 1051640
349 + 1051291 = 1051640
463 + 1051177 = 1051640
487 + 1051153 = 1051640

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 5, 1640 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1640-05-01 (DMMYYYY (Euro, single-digit day))
1640-10-05 (MMDYYYY (US, single-digit day))
1640-05-10 (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 1,051,640 and was likely granted around 1912.

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