Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542696, here are decompositions:
- 19 + 31542677 = 31542696
- 37 + 31542659 = 31542696
- 83 + 31542613 = 31542696
- 109 + 31542587 = 31542696
- 137 + 31542559 = 31542696
- 149 + 31542547 = 31542696
- 173 + 31542523 = 31542696
- 239 + 31542457 = 31542696
Showing the first eight; more decompositions exist.
