Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545584, here are decompositions:
- 97 + 31545487 = 31545584
- 193 + 31545391 = 31545584
- 211 + 31545373 = 31545584
- 241 + 31545343 = 31545584
- 373 + 31545211 = 31545584
- 487 + 31545097 = 31545584
- 523 + 31545061 = 31545584
- 643 + 31544941 = 31545584
Showing the first eight; more decompositions exist.
