Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662660, here are decompositions:

3 + 8662657 = 8662660
11 + 8662649 = 8662660
107 + 8662553 = 8662660
173 + 8662487 = 8662660
179 + 8662481 = 8662660
263 + 8662397 = 8662660
311 + 8662349 = 8662660
317 + 8662343 = 8662660

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 8,662,660 and was likely granted around 2014.

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