Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620000, here are decompositions:

3 + 8619997 = 8620000
107 + 8619893 = 8620000
131 + 8619869 = 8620000
227 + 8619773 = 8620000
281 + 8619719 = 8620000
317 + 8619683 = 8620000
449 + 8619551 = 8620000
461 + 8619539 = 8620000

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 8,620,000 and was likely granted around 2013.

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