Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563566, here are decompositions:
- 103 + 31563463 = 31563566
- 163 + 31563403 = 31563566
- 283 + 31563283 = 31563566
- 313 + 31563253 = 31563566
- 373 + 31563193 = 31563566
- 379 + 31563187 = 31563566
- 439 + 31563127 = 31563566
- 523 + 31563043 = 31563566
Showing the first eight; more decompositions exist.
