Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684642, here are decompositions:
- 13 + 8684629 = 8684642
- 139 + 8684503 = 8684642
- 163 + 8684479 = 8684642
- 181 + 8684461 = 8684642
- 223 + 8684419 = 8684642
- 283 + 8684359 = 8684642
- 313 + 8684329 = 8684642
- 613 + 8684029 = 8684642
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 8,684,642 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
