Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545358, here are decompositions:
- 29 + 31545329 = 31545358
- 41 + 31545317 = 31545358
- 59 + 31545299 = 31545358
- 71 + 31545287 = 31545358
- 137 + 31545221 = 31545358
- 167 + 31545191 = 31545358
- 239 + 31545119 = 31545358
- 389 + 31544969 = 31545358
Showing the first eight; more decompositions exist.
