Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545312, here are decompositions:
- 13 + 31545299 = 31545312
- 79 + 31545233 = 31545312
- 101 + 31545211 = 31545312
- 131 + 31545181 = 31545312
- 193 + 31545119 = 31545312
- 229 + 31545083 = 31545312
- 251 + 31545061 = 31545312
- 263 + 31545049 = 31545312
Showing the first eight; more decompositions exist.
