Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613100, here are decompositions:

11 + 8613089 = 8613100
53 + 8613047 = 8613100
59 + 8613041 = 8613100
131 + 8612969 = 8613100
173 + 8612927 = 8613100
227 + 8612873 = 8613100
239 + 8612861 = 8613100
263 + 8612837 = 8613100

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 8,613,100 and was likely granted around 2013.

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