Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684440, here are decompositions:
- 3 + 8684437 = 8684440
- 29 + 8684411 = 8684440
- 173 + 8684267 = 8684440
- 179 + 8684261 = 8684440
- 197 + 8684243 = 8684440
- 227 + 8684213 = 8684440
- 239 + 8684201 = 8684440
- 251 + 8684189 = 8684440
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 8,684,440 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
