Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533832, here are decompositions:
- 3 + 31533829 = 31533832
- 41 + 31533791 = 31533832
- 59 + 31533773 = 31533832
- 173 + 31533659 = 31533832
- 191 + 31533641 = 31533832
- 233 + 31533599 = 31533832
- 251 + 31533581 = 31533832
- 269 + 31533563 = 31533832
Showing the first eight; more decompositions exist.
