Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672666, here are decompositions:
- 7 + 8672659 = 8672666
- 19 + 8672647 = 8672666
- 103 + 8672563 = 8672666
- 127 + 8672539 = 8672666
- 139 + 8672527 = 8672666
- 157 + 8672509 = 8672666
- 313 + 8672353 = 8672666
- 463 + 8672203 = 8672666
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 8,672,666 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
