Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687166, here are decompositions:

17 + 8687149 = 8687166
73 + 8687093 = 8687166
79 + 8687087 = 8687166
97 + 8687069 = 8687166
139 + 8687027 = 8687166
167 + 8686999 = 8687166
277 + 8686889 = 8687166
283 + 8686883 = 8687166

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 8,687,166 and was likely granted around 2014.

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