Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051500, here are decompositions:

19 + 1051481 = 1051500
29 + 1051471 = 1051500
31 + 1051469 = 1051500
41 + 1051459 = 1051500
83 + 1051417 = 1051500
103 + 1051397 = 1051500
127 + 1051373 = 1051500
167 + 1051333 = 1051500

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 1500 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1500-05-01 (DMMYYYY (Euro, single-digit day))
1500-10-05 (MMDYYYY (US, single-digit day))
1500-05-10 (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 1,051,500 and was likely granted around 1912.

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