Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667000, here are decompositions:
- 7 + 8666993 = 8667000
- 11 + 8666989 = 8667000
- 47 + 8666953 = 8667000
- 61 + 8666939 = 8667000
- 73 + 8666927 = 8667000
- 109 + 8666891 = 8667000
- 137 + 8666863 = 8667000
- 151 + 8666849 = 8667000
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 8,667,000 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
