Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534660, here are decompositions:
- 23 + 31534637 = 31534660
- 29 + 31534631 = 31534660
- 71 + 31534589 = 31534660
- 107 + 31534553 = 31534660
- 167 + 31534493 = 31534660
- 173 + 31534487 = 31534660
- 233 + 31534427 = 31534660
- 317 + 31534343 = 31534660
Showing the first eight; more decompositions exist.
