Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533838, here are decompositions:
- 5 + 31533833 = 31533838
- 47 + 31533791 = 31533838
- 131 + 31533707 = 31533838
- 179 + 31533659 = 31533838
- 197 + 31533641 = 31533838
- 227 + 31533611 = 31533838
- 239 + 31533599 = 31533838
- 251 + 31533587 = 31533838
Showing the first eight; more decompositions exist.
