Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673866, here are decompositions:

139 + 8673727 = 8673866
163 + 8673703 = 8673866
349 + 8673517 = 8673866
367 + 8673499 = 8673866
433 + 8673433 = 8673866
709 + 8673157 = 8673866
739 + 8673127 = 8673866
757 + 8673109 = 8673866

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 8,673,866 and was likely granted around 2014.

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