Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545340, here are decompositions:
- 11 + 31545329 = 31545340
- 17 + 31545323 = 31545340
- 23 + 31545317 = 31545340
- 41 + 31545299 = 31545340
- 53 + 31545287 = 31545340
- 107 + 31545233 = 31545340
- 149 + 31545191 = 31545340
- 257 + 31545083 = 31545340
Showing the first eight; more decompositions exist.
