Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545238, here are decompositions:
- 5 + 31545233 = 31545238
- 17 + 31545221 = 31545238
- 47 + 31545191 = 31545238
- 269 + 31544969 = 31545238
- 359 + 31544879 = 31545238
- 419 + 31544819 = 31545238
- 467 + 31544771 = 31545238
- 479 + 31544759 = 31545238
Showing the first eight; more decompositions exist.
