Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621330, here are decompositions:
- 11 + 31621319 = 31621330
- 71 + 31621259 = 31621330
- 101 + 31621229 = 31621330
- 113 + 31621217 = 31621330
- 173 + 31621157 = 31621330
- 179 + 31621151 = 31621330
- 197 + 31621133 = 31621330
- 233 + 31621097 = 31621330
Showing the first eight; more decompositions exist.
