Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538694, here are decompositions:
- 23 + 31538671 = 31538694
- 41 + 31538653 = 31538694
- 53 + 31538641 = 31538694
- 71 + 31538623 = 31538694
- 113 + 31538581 = 31538694
- 137 + 31538557 = 31538694
- 167 + 31538527 = 31538694
- 191 + 31538503 = 31538694
Showing the first eight; more decompositions exist.
