Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664668, here are decompositions:

7 + 8664661 = 8664668
109 + 8664559 = 8664668
139 + 8664529 = 8664668
151 + 8664517 = 8664668
241 + 8664427 = 8664668
409 + 8664259 = 8664668
487 + 8664181 = 8664668
631 + 8664037 = 8664668

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 8,664,668 and was likely granted around 2014.

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