Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681188, here are decompositions:

11 + 8681177 = 8681188
29 + 8681159 = 8681188
59 + 8681129 = 8681188
71 + 8681117 = 8681188
167 + 8681021 = 8681188
179 + 8681009 = 8681188
281 + 8680907 = 8681188
317 + 8680871 = 8681188

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 8 681 188 and was likely granted around 2014.

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