Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670940, here are decompositions:

53 + 8670887 = 8670940
71 + 8670869 = 8670940
149 + 8670791 = 8670940
167 + 8670773 = 8670940
197 + 8670743 = 8670940
227 + 8670713 = 8670940
389 + 8670551 = 8670940
431 + 8670509 = 8670940

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 8,670,940 and was likely granted around 2014.

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