Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664120, here are decompositions:
- 11 + 8664109 = 8664120
- 13 + 8664107 = 8664120
- 67 + 8664053 = 8664120
- 83 + 8664037 = 8664120
- 97 + 8664023 = 8664120
- 151 + 8663969 = 8664120
- 197 + 8663923 = 8664120
- 251 + 8663869 = 8664120
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 8,664,120 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
