Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31384, here are decompositions:
- 5 + 31379 = 31384
- 47 + 31337 = 31384
- 107 + 31277 = 31384
- 113 + 31271 = 31384
- 131 + 31253 = 31384
- 137 + 31247 = 31384
- 191 + 31193 = 31384
- 233 + 31151 = 31384
Showing the first eight; more decompositions exist.
