Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664864, here are decompositions:
- 7 + 8664857 = 8664864
- 17 + 8664847 = 8664864
- 73 + 8664791 = 8664864
- 107 + 8664757 = 8664864
- 163 + 8664701 = 8664864
- 193 + 8664671 = 8664864
- 251 + 8664613 = 8664864
- 283 + 8664581 = 8664864
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 8,664,864 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
