Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680668, here are decompositions:

37 + 8680631 = 8680668
67 + 8680601 = 8680668
109 + 8680559 = 8680668
167 + 8680501 = 8680668
197 + 8680471 = 8680668
229 + 8680439 = 8680668
251 + 8680417 = 8680668
277 + 8680391 = 8680668

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 8 680 668 and was likely granted around 2014.

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