Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684840, here are decompositions:
- 19 + 8684821 = 8684840
- 79 + 8684761 = 8684840
- 127 + 8684713 = 8684840
- 211 + 8684629 = 8684840
- 337 + 8684503 = 8684840
- 379 + 8684461 = 8684840
- 421 + 8684419 = 8684840
- 433 + 8684407 = 8684840
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 8,684,840 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
