Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662628, here are decompositions:

31 + 8662597 = 8662628
97 + 8662531 = 8662628
157 + 8662471 = 8662628
181 + 8662447 = 8662628
349 + 8662279 = 8662628
379 + 8662249 = 8662628
409 + 8662219 = 8662628
439 + 8662189 = 8662628

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 8,662,628 and was likely granted around 2014.

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