Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669618, here are decompositions:

7 + 8669611 = 8669618
229 + 8669389 = 8669618
277 + 8669341 = 8669618
367 + 8669251 = 8669618
379 + 8669239 = 8669618
439 + 8669179 = 8669618
547 + 8669071 = 8669618
577 + 8669041 = 8669618

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 8,669,618 and was likely granted around 2014.

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