Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666938, here are decompositions:

11 + 8666927 = 8666938
47 + 8666891 = 8666938
89 + 8666849 = 8666938
131 + 8666807 = 8666938
191 + 8666747 = 8666938
227 + 8666711 = 8666938
257 + 8666681 = 8666938
311 + 8666627 = 8666938

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 8 666 938 and was likely granted around 2014.

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