Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667512, here are decompositions:
- 109 + 8667403 = 8667512
- 163 + 8667349 = 8667512
- 193 + 8667319 = 8667512
- 199 + 8667313 = 8667512
- 211 + 8667301 = 8667512
- 223 + 8667289 = 8667512
- 241 + 8667271 = 8667512
- 409 + 8667103 = 8667512
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 8,667,512 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
