Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031512, here are decompositions:

5 + 1031507 = 1031512
23 + 1031489 = 1031512
29 + 1031483 = 1031512
89 + 1031423 = 1031512
101 + 1031411 = 1031512
113 + 1031399 = 1031512
233 + 1031279 = 1031512
281 + 1031231 = 1031512

Showing the first eight; more decompositions exist.

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 1,031,512 and was likely granted around 1912.

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