Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687690, here are decompositions:

3 + 8687687 = 8687690
19 + 8687671 = 8687690
31 + 8687659 = 8687690
103 + 8687587 = 8687690
211 + 8687479 = 8687690
223 + 8687467 = 8687690
229 + 8687461 = 8687690
307 + 8687383 = 8687690

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 8,687,690 and was likely granted around 2014.

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