Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600640, here are decompositions:

7 + 8600633 = 8600640
11 + 8600629 = 8600640
19 + 8600621 = 8600640
47 + 8600593 = 8600640
53 + 8600587 = 8600640
107 + 8600533 = 8600640
131 + 8600509 = 8600640
149 + 8600491 = 8600640

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 8,600,640 and was likely granted around 2013.

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