Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662644, here are decompositions:

47 + 8662597 = 8662644
61 + 8662583 = 8662644
103 + 8662541 = 8662644
113 + 8662531 = 8662644
127 + 8662517 = 8662644
157 + 8662487 = 8662644
163 + 8662481 = 8662644
173 + 8662471 = 8662644

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 8,662,644 and was likely granted around 2014.

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