Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545224, here are decompositions:
- 3 + 31545221 = 31545224
- 13 + 31545211 = 31545224
- 43 + 31545181 = 31545224
- 127 + 31545097 = 31545224
- 157 + 31545067 = 31545224
- 163 + 31545061 = 31545224
- 223 + 31545001 = 31545224
- 283 + 31544941 = 31545224
Showing the first eight; more decompositions exist.
