Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534686, here are decompositions:
- 17 + 31534669 = 31534686
- 89 + 31534597 = 31534686
- 97 + 31534589 = 31534686
- 193 + 31534493 = 31534686
- 199 + 31534487 = 31534686
- 229 + 31534457 = 31534686
- 257 + 31534429 = 31534686
- 263 + 31534423 = 31534686
Showing the first eight; more decompositions exist.
