Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545232, here are decompositions:
- 11 + 31545221 = 31545232
- 41 + 31545191 = 31545232
- 113 + 31545119 = 31545232
- 149 + 31545083 = 31545232
- 263 + 31544969 = 31545232
- 269 + 31544963 = 31545232
- 353 + 31544879 = 31545232
- 449 + 31544783 = 31545232
Showing the first eight; more decompositions exist.
