Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538834, here are decompositions:
- 7 + 31538827 = 31538834
- 163 + 31538671 = 31538834
- 181 + 31538653 = 31538834
- 193 + 31538641 = 31538834
- 211 + 31538623 = 31538834
- 277 + 31538557 = 31538834
- 307 + 31538527 = 31538834
- 331 + 31538503 = 31538834
Showing the first eight; more decompositions exist.
