Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530696, here are decompositions:
- 13 + 31530683 = 31530696
- 17 + 31530679 = 31530696
- 37 + 31530659 = 31530696
- 47 + 31530649 = 31530696
- 53 + 31530643 = 31530696
- 59 + 31530637 = 31530696
- 79 + 31530617 = 31530696
- 89 + 31530607 = 31530696
Showing the first eight; more decompositions exist.
