Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545448, here are decompositions:
- 41 + 31545407 = 31545448
- 47 + 31545401 = 31545448
- 131 + 31545317 = 31545448
- 149 + 31545299 = 31545448
- 227 + 31545221 = 31545448
- 257 + 31545191 = 31545448
- 479 + 31544969 = 31545448
- 569 + 31544879 = 31545448
Showing the first eight; more decompositions exist.
