Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533804, here are decompositions:
- 13 + 31533791 = 31533804
- 31 + 31533773 = 31533804
- 41 + 31533763 = 31533804
- 83 + 31533721 = 31533804
- 97 + 31533707 = 31533804
- 163 + 31533641 = 31533804
- 167 + 31533637 = 31533804
- 173 + 31533631 = 31533804
Showing the first eight; more decompositions exist.
