Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680778, here are decompositions:

37 + 8680741 = 8680778
61 + 8680717 = 8680778
79 + 8680699 = 8680778
109 + 8680669 = 8680778
277 + 8680501 = 8680778
307 + 8680471 = 8680778
409 + 8680369 = 8680778
577 + 8680201 = 8680778

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 8 680 778 and was likely granted around 2014.

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