Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675440, here are decompositions:

41 + 8675399 = 8675440
83 + 8675357 = 8675440
113 + 8675327 = 8675440
131 + 8675309 = 8675440
251 + 8675189 = 8675440
419 + 8675021 = 8675440
479 + 8674961 = 8675440
503 + 8674937 = 8675440

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 8,675,440 and was likely granted around 2014.

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