Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667872, here are decompositions:

43 + 8667829 = 8667872
79 + 8667793 = 8667872
139 + 8667733 = 8667872
151 + 8667721 = 8667872
211 + 8667661 = 8667872
271 + 8667601 = 8667872
313 + 8667559 = 8667872
523 + 8667349 = 8667872

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 8 667 872 and was likely granted around 2014.

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