Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671318, here are decompositions:

11 + 8671307 = 8671318
167 + 8671151 = 8671318
191 + 8671127 = 8671318
251 + 8671067 = 8671318
311 + 8671007 = 8671318
431 + 8670887 = 8671318
449 + 8670869 = 8671318
809 + 8670509 = 8671318

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 8,671,318 and was likely granted around 2014.

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