Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684672, here are decompositions:
- 43 + 8684629 = 8684672
- 151 + 8684521 = 8684672
- 193 + 8684479 = 8684672
- 211 + 8684461 = 8684672
- 313 + 8684359 = 8684672
- 331 + 8684341 = 8684672
- 499 + 8684173 = 8684672
- 541 + 8684131 = 8684672
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 8,684,672 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
