Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674140, here are decompositions:

31 + 8674109 = 8674140
53 + 8674087 = 8674140
71 + 8674069 = 8674140
103 + 8674037 = 8674140
131 + 8674009 = 8674140
151 + 8673989 = 8674140
199 + 8673941 = 8674140
227 + 8673913 = 8674140

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 8,674,140 and was likely granted around 2014.

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