Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672668, here are decompositions:
- 29 + 8672639 = 8672668
- 47 + 8672621 = 8672668
- 71 + 8672597 = 8672668
- 107 + 8672561 = 8672668
- 149 + 8672519 = 8672668
- 167 + 8672501 = 8672668
- 197 + 8672471 = 8672668
- 227 + 8672441 = 8672668
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 8,672,668 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
