Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533882, here are decompositions:
- 11 + 31533871 = 31533882
- 43 + 31533839 = 31533882
- 53 + 31533829 = 31533882
- 59 + 31533823 = 31533882
- 109 + 31533773 = 31533882
- 113 + 31533769 = 31533882
- 223 + 31533659 = 31533882
- 241 + 31533641 = 31533882
Showing the first eight; more decompositions exist.
