Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667808, here are decompositions:
- 11 + 8667797 = 8667808
- 101 + 8667707 = 8667808
- 131 + 8667677 = 8667808
- 167 + 8667641 = 8667808
- 197 + 8667611 = 8667808
- 269 + 8667539 = 8667808
- 311 + 8667497 = 8667808
- 389 + 8667419 = 8667808
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 8,667,808 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
