Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664660, here are decompositions:
- 47 + 8664613 = 8664660
- 79 + 8664581 = 8664660
- 101 + 8664559 = 8664660
- 107 + 8664553 = 8664660
- 113 + 8664547 = 8664660
- 131 + 8664529 = 8664660
- 227 + 8664433 = 8664660
- 229 + 8664431 = 8664660
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 8,664,660 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
