Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666764, here are decompositions:
- 17 + 8666747 = 8666764
- 53 + 8666711 = 8666764
- 83 + 8666681 = 8666764
- 137 + 8666627 = 8666764
- 167 + 8666597 = 8666764
- 173 + 8666591 = 8666764
- 251 + 8666513 = 8666764
- 263 + 8666501 = 8666764
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 8,666,764 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
