Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530708, here are decompositions:
- 5 + 31530703 = 31530708
- 7 + 31530701 = 31530708
- 29 + 31530679 = 31530708
- 47 + 31530661 = 31530708
- 59 + 31530649 = 31530708
- 67 + 31530641 = 31530708
- 71 + 31530637 = 31530708
- 101 + 31530607 = 31530708
Showing the first eight; more decompositions exist.
