Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680228, here are decompositions:

41 + 8680187 = 8680228
71 + 8680157 = 8680228
107 + 8680121 = 8680228
191 + 8680037 = 8680228
257 + 8679971 = 8680228
461 + 8679767 = 8680228
587 + 8679641 = 8680228
647 + 8679581 = 8680228

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 8,680,228 and was likely granted around 2014.

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