Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684684, here are decompositions:
- 97 + 8684587 = 8684684
- 163 + 8684521 = 8684684
- 181 + 8684503 = 8684684
- 223 + 8684461 = 8684684
- 277 + 8684407 = 8684684
- 577 + 8684107 = 8684684
- 607 + 8684077 = 8684684
- 661 + 8684023 = 8684684
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 8,684,684 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
