Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031812, here are decompositions:

3 + 1031809 = 1031812
53 + 1031759 = 1031812
59 + 1031753 = 1031812
71 + 1031741 = 1031812
83 + 1031729 = 1031812
179 + 1031633 = 1031812
251 + 1031561 = 1031812
263 + 1031549 = 1031812

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 1,031,812 and was likely granted around 1912.

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