Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518670, here are decompositions:
- 11 + 31518659 = 31518670
- 17 + 31518653 = 31518670
- 23 + 31518647 = 31518670
- 149 + 31518521 = 31518670
- 179 + 31518491 = 31518670
- 317 + 31518353 = 31518670
- 383 + 31518287 = 31518670
- 389 + 31518281 = 31518670
Showing the first eight; more decompositions exist.
