Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664624, here are decompositions:
- 11 + 8664613 = 8664624
- 43 + 8664581 = 8664624
- 71 + 8664553 = 8664624
- 97 + 8664527 = 8664624
- 107 + 8664517 = 8664624
- 151 + 8664473 = 8664624
- 173 + 8664451 = 8664624
- 191 + 8664433 = 8664624
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 8,664,624 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
