Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533790, here are decompositions:
- 17 + 31533773 = 31533790
- 83 + 31533707 = 31533790
- 131 + 31533659 = 31533790
- 149 + 31533641 = 31533790
- 179 + 31533611 = 31533790
- 191 + 31533599 = 31533790
- 227 + 31533563 = 31533790
- 257 + 31533533 = 31533790
Showing the first eight; more decompositions exist.
