Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672650, here are decompositions:

3 + 8672647 = 8672650
11 + 8672639 = 8672650
29 + 8672621 = 8672650
53 + 8672597 = 8672650
89 + 8672561 = 8672650
131 + 8672519 = 8672650
137 + 8672513 = 8672650
149 + 8672501 = 8672650

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 8,672,650 and was likely granted around 2014.

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