Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686442, here are decompositions:

73 + 8686369 = 8686442
151 + 8686291 = 8686442
229 + 8686213 = 8686442
283 + 8686159 = 8686442
439 + 8686003 = 8686442
463 + 8685979 = 8686442
673 + 8685769 = 8686442
691 + 8685751 = 8686442

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 8,686,442 and was likely granted around 2014.

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