Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660100, here are decompositions:

13 + 8660087 = 8660100
19 + 8660081 = 8660100
23 + 8660077 = 8660100
47 + 8660053 = 8660100
61 + 8660039 = 8660100
67 + 8660033 = 8660100
101 + 8659999 = 8660100
103 + 8659997 = 8660100

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 8,660,100 and was likely granted around 2014.

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