Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530710, here are decompositions:
- 7 + 31530703 = 31530710
- 31 + 31530679 = 31530710
- 61 + 31530649 = 31530710
- 67 + 31530643 = 31530710
- 73 + 31530637 = 31530710
- 103 + 31530607 = 31530710
- 139 + 31530571 = 31530710
- 223 + 31530487 = 31530710
Showing the first eight; more decompositions exist.
