Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684426, here are decompositions:
- 7 + 8684419 = 8684426
- 19 + 8684407 = 8684426
- 67 + 8684359 = 8684426
- 97 + 8684329 = 8684426
- 337 + 8684089 = 8684426
- 349 + 8684077 = 8684426
- 379 + 8684047 = 8684426
- 397 + 8684029 = 8684426
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 8,684,426 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
