Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8384, here are decompositions:
- 7 + 8377 = 8384
- 31 + 8353 = 8384
- 67 + 8317 = 8384
- 73 + 8311 = 8384
- 97 + 8287 = 8384
- 151 + 8233 = 8384
- 163 + 8221 = 8384
- 193 + 8191 = 8384
Showing the first eight; more decompositions exist.
