Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557708, here are decompositions:
- 5 + 31557703 = 31557708
- 11 + 31557697 = 31557708
- 31 + 31557677 = 31557708
- 37 + 31557671 = 31557708
- 59 + 31557649 = 31557708
- 71 + 31557637 = 31557708
- 97 + 31557611 = 31557708
- 107 + 31557601 = 31557708
Showing the first eight; more decompositions exist.
