Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642384, here are decompositions:
- 103 + 8642281 = 8642384
- 211 + 8642173 = 8642384
- 277 + 8642107 = 8642384
- 307 + 8642077 = 8642384
- 397 + 8641987 = 8642384
- 577 + 8641807 = 8642384
- 601 + 8641783 = 8642384
- 643 + 8641741 = 8642384
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 8,642,384 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
