Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700000, here are decompositions:

7 + 8699993 = 8700000
19 + 8699981 = 8700000
31 + 8699969 = 8700000
41 + 8699959 = 8700000
47 + 8699953 = 8700000
53 + 8699947 = 8700000
83 + 8699917 = 8700000
107 + 8699893 = 8700000

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 8,700,000 and was likely granted around 2014.

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