Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539696, here are decompositions:
- 37 + 31539659 = 31539696
- 47 + 31539649 = 31539696
- 53 + 31539643 = 31539696
- 103 + 31539593 = 31539696
- 109 + 31539587 = 31539696
- 113 + 31539583 = 31539696
- 127 + 31539569 = 31539696
- 173 + 31539523 = 31539696
Showing the first eight; more decompositions exist.
