Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538634, here are decompositions:
- 5 + 31538629 = 31538634
- 11 + 31538623 = 31538634
- 53 + 31538581 = 31538634
- 73 + 31538561 = 31538634
- 107 + 31538527 = 31538634
- 131 + 31538503 = 31538634
- 157 + 31538477 = 31538634
- 191 + 31538443 = 31538634
Showing the first eight; more decompositions exist.
