Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678668, here are decompositions:
- 29 + 8678639 = 8678668
- 149 + 8678519 = 8678668
- 269 + 8678399 = 8678668
- 431 + 8678237 = 8678668
- 521 + 8678147 = 8678668
- 587 + 8678081 = 8678668
- 599 + 8678069 = 8678668
- 617 + 8678051 = 8678668
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 8,678,668 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
