Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533744, here are decompositions:
- 23 + 31533721 = 31533744
- 37 + 31533707 = 31533744
- 83 + 31533661 = 31533744
- 103 + 31533641 = 31533744
- 107 + 31533637 = 31533744
- 113 + 31533631 = 31533744
- 131 + 31533613 = 31533744
- 157 + 31533587 = 31533744
Showing the first eight; more decompositions exist.
