Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542600, here are decompositions:
- 13 + 31542587 = 31542600
- 41 + 31542559 = 31542600
- 53 + 31542547 = 31542600
- 113 + 31542487 = 31542600
- 163 + 31542437 = 31542600
- 181 + 31542419 = 31542600
- 223 + 31542377 = 31542600
- 227 + 31542373 = 31542600
Showing the first eight; more decompositions exist.
