Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545252, here are decompositions:
- 19 + 31545233 = 31545252
- 31 + 31545221 = 31545252
- 41 + 31545211 = 31545252
- 61 + 31545191 = 31545252
- 71 + 31545181 = 31545252
- 191 + 31545061 = 31545252
- 229 + 31545023 = 31545252
- 251 + 31545001 = 31545252
Showing the first eight; more decompositions exist.
