Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668008, here are decompositions:
- 7 + 8668001 = 8668008
- 29 + 8667979 = 8668008
- 47 + 8667961 = 8668008
- 59 + 8667949 = 8668008
- 79 + 8667929 = 8668008
- 101 + 8667907 = 8668008
- 109 + 8667899 = 8668008
- 137 + 8667871 = 8668008
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8 668 008 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
