Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522824, here are decompositions:
- 107 + 31522717 = 31522824
- 131 + 31522693 = 31522824
- 167 + 31522657 = 31522824
- 191 + 31522633 = 31522824
- 211 + 31522613 = 31522824
- 227 + 31522597 = 31522824
- 233 + 31522591 = 31522824
- 241 + 31522583 = 31522824
Showing the first eight; more decompositions exist.
