Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589712, here are decompositions:
- 5 + 31589707 = 31589712
- 19 + 31589693 = 31589712
- 29 + 31589683 = 31589712
- 53 + 31589659 = 31589712
- 79 + 31589633 = 31589712
- 101 + 31589611 = 31589712
- 151 + 31589561 = 31589712
- 173 + 31589539 = 31589712
Showing the first eight; more decompositions exist.
