Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668020, here are decompositions:

19 + 8668001 = 8668020
41 + 8667979 = 8668020
47 + 8667973 = 8668020
59 + 8667961 = 8668020
71 + 8667949 = 8668020
89 + 8667931 = 8668020
107 + 8667913 = 8668020
113 + 8667907 = 8668020

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 8 668 020 and was likely granted around 2014.

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