Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533948, here are decompositions:
- 29 + 31533919 = 31533948
- 37 + 31533911 = 31533948
- 101 + 31533847 = 31533948
- 109 + 31533839 = 31533948
- 157 + 31533791 = 31533948
- 179 + 31533769 = 31533948
- 227 + 31533721 = 31533948
- 241 + 31533707 = 31533948
Showing the first eight; more decompositions exist.
