Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672906, here are decompositions:

37 + 8672869 = 8672906
127 + 8672779 = 8672906
139 + 8672767 = 8672906
199 + 8672707 = 8672906
367 + 8672539 = 8672906
379 + 8672527 = 8672906
397 + 8672509 = 8672906
499 + 8672407 = 8672906

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 8,672,906 and was likely granted around 2014.

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