Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678272, here are decompositions:

59 + 8678213 = 8678272
131 + 8678141 = 8678272
179 + 8678093 = 8678272
191 + 8678081 = 8678272
233 + 8678039 = 8678272
293 + 8677979 = 8678272
311 + 8677961 = 8678272
389 + 8677883 = 8678272

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 8,678,272 and was likely granted around 2014.

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