Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687384, here are decompositions:
- 3 + 8687381 = 8687384
- 67 + 8687317 = 8687384
- 151 + 8687233 = 8687384
- 157 + 8687227 = 8687384
- 577 + 8686807 = 8687384
- 733 + 8686651 = 8687384
- 883 + 8686501 = 8687384
- 1087 + 8686297 = 8687384
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 8,687,384 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
