Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539762, here are decompositions:
- 5 + 31539757 = 31539762
- 101 + 31539661 = 31539762
- 103 + 31539659 = 31539762
- 113 + 31539649 = 31539762
- 179 + 31539583 = 31539762
- 193 + 31539569 = 31539762
- 239 + 31539523 = 31539762
- 263 + 31539499 = 31539762
Showing the first eight; more decompositions exist.
