Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462, here are decompositions:
- 71 + 31391 = 31462
- 83 + 31379 = 31462
- 191 + 31271 = 31462
- 239 + 31223 = 31462
- 269 + 31193 = 31462
- 281 + 31181 = 31462
- 311 + 31151 = 31462
- 383 + 31079 = 31462
Showing the first eight; more decompositions exist.
