Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534636, here are decompositions:
- 5 + 31534631 = 31534636
- 47 + 31534589 = 31534636
- 83 + 31534553 = 31534636
- 149 + 31534487 = 31534636
- 179 + 31534457 = 31534636
- 293 + 31534343 = 31534636
- 389 + 31534247 = 31534636
- 449 + 31534187 = 31534636
Showing the first eight; more decompositions exist.
