Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545336, here are decompositions:
- 5 + 31545331 = 31545336
- 7 + 31545329 = 31545336
- 13 + 31545323 = 31545336
- 19 + 31545317 = 31545336
- 37 + 31545299 = 31545336
- 103 + 31545233 = 31545336
- 239 + 31545097 = 31545336
- 269 + 31545067 = 31545336
Showing the first eight; more decompositions exist.
