Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660000, here are decompositions:

3 + 8659997 = 8660000
43 + 8659957 = 8660000
61 + 8659939 = 8660000
73 + 8659927 = 8660000
79 + 8659921 = 8660000
127 + 8659873 = 8660000
163 + 8659837 = 8660000
331 + 8659669 = 8660000

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 8,660,000 and was likely granted around 2014.

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