Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533768, here are decompositions:
- 5 + 31533763 = 31533768
- 47 + 31533721 = 31533768
- 61 + 31533707 = 31533768
- 107 + 31533661 = 31533768
- 109 + 31533659 = 31533768
- 127 + 31533641 = 31533768
- 131 + 31533637 = 31533768
- 137 + 31533631 = 31533768
Showing the first eight; more decompositions exist.
