Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545322, here are decompositions:
- 5 + 31545317 = 31545322
- 23 + 31545299 = 31545322
- 89 + 31545233 = 31545322
- 101 + 31545221 = 31545322
- 131 + 31545191 = 31545322
- 239 + 31545083 = 31545322
- 353 + 31544969 = 31545322
- 359 + 31544963 = 31545322
Showing the first eight; more decompositions exist.
