Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667120, here are decompositions:
- 17 + 8667103 = 8667120
- 41 + 8667079 = 8667120
- 127 + 8666993 = 8667120
- 131 + 8666989 = 8667120
- 167 + 8666953 = 8667120
- 181 + 8666939 = 8667120
- 193 + 8666927 = 8667120
- 229 + 8666891 = 8667120
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 8,667,120 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
