Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678188, here are decompositions:

41 + 8678147 = 8678188
47 + 8678141 = 8678188
59 + 8678129 = 8678188
107 + 8678081 = 8678188
131 + 8678057 = 8678188
137 + 8678051 = 8678188
149 + 8678039 = 8678188
227 + 8677961 = 8678188

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 8,678,188 and was likely granted around 2014.

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