Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 322, here are decompositions:
- 5 + 317 = 322
- 11 + 311 = 322
- 29 + 293 = 322
- 41 + 281 = 322
- 53 + 269 = 322
- 59 + 263 = 322
- 71 + 251 = 322
- 83 + 239 = 322
Showing the first eight; more decompositions exist.
