Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672812, here are decompositions:

11 + 8672801 = 8672812
23 + 8672789 = 8672812
89 + 8672723 = 8672812
173 + 8672639 = 8672812
191 + 8672621 = 8672812
251 + 8672561 = 8672812
293 + 8672519 = 8672812
311 + 8672501 = 8672812

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 8,672,812 and was likely granted around 2014.

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