Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687140, here are decompositions:

23 + 8687117 = 8687140
47 + 8687093 = 8687140
53 + 8687087 = 8687140
71 + 8687069 = 8687140
113 + 8687027 = 8687140
179 + 8686961 = 8687140
239 + 8686901 = 8687140
251 + 8686889 = 8687140

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 8,687,140 and was likely granted around 2014.

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