Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542750, here are decompositions:
- 23 + 31542727 = 31542750
- 47 + 31542703 = 31542750
- 53 + 31542697 = 31542750
- 73 + 31542677 = 31542750
- 137 + 31542613 = 31542750
- 163 + 31542587 = 31542750
- 191 + 31542559 = 31542750
- 227 + 31542523 = 31542750
Showing the first eight; more decompositions exist.
