Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687946, here are decompositions:

17 + 8687929 = 8687946
23 + 8687923 = 8687946
67 + 8687879 = 8687946
73 + 8687873 = 8687946
149 + 8687797 = 8687946
233 + 8687713 = 8687946
277 + 8687669 = 8687946
347 + 8687599 = 8687946

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 8,687,946 and was likely granted around 2014.

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