Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678684, here are decompositions:
- 13 + 8678671 = 8678684
- 97 + 8678587 = 8678684
- 103 + 8678581 = 8678684
- 127 + 8678557 = 8678684
- 211 + 8678473 = 8678684
- 331 + 8678353 = 8678684
- 373 + 8678311 = 8678684
- 523 + 8678161 = 8678684
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 8,678,684 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
