Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678560, here are decompositions:

3 + 8678557 = 8678560
41 + 8678519 = 8678560
53 + 8678507 = 8678560
113 + 8678447 = 8678560
167 + 8678393 = 8678560
197 + 8678363 = 8678560
227 + 8678333 = 8678560
347 + 8678213 = 8678560

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 8,678,560 and was likely granted around 2014.

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