Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664320, here are decompositions:
- 3 + 8664317 = 8664320
- 61 + 8664259 = 8664320
- 97 + 8664223 = 8664320
- 127 + 8664193 = 8664320
- 139 + 8664181 = 8664320
- 163 + 8664157 = 8664320
- 211 + 8664109 = 8664320
- 277 + 8664043 = 8664320
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 8,664,320 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
