Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663664, here are decompositions:
- 11 + 8663653 = 8663664
- 43 + 8663621 = 8663664
- 71 + 8663593 = 8663664
- 127 + 8663537 = 8663664
- 157 + 8663507 = 8663664
- 167 + 8663497 = 8663664
- 193 + 8663471 = 8663664
- 197 + 8663467 = 8663664
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 8,663,664 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
