Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686646, here are decompositions:

79 + 8686567 = 8686646
277 + 8686369 = 8686646
337 + 8686309 = 8686646
349 + 8686297 = 8686646
373 + 8686273 = 8686646
433 + 8686213 = 8686646
439 + 8686207 = 8686646
457 + 8686189 = 8686646

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 8,686,646 and was likely granted around 2014.

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