Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533678, here are decompositions:
- 17 + 31533661 = 31533678
- 19 + 31533659 = 31533678
- 37 + 31533641 = 31533678
- 41 + 31533637 = 31533678
- 47 + 31533631 = 31533678
- 67 + 31533611 = 31533678
- 79 + 31533599 = 31533678
- 97 + 31533581 = 31533678
Showing the first eight; more decompositions exist.
