Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530768, here are decompositions:
- 67 + 31530701 = 31530768
- 89 + 31530679 = 31530768
- 107 + 31530661 = 31530768
- 109 + 31530659 = 31530768
- 127 + 31530641 = 31530768
- 131 + 31530637 = 31530768
- 151 + 31530617 = 31530768
- 179 + 31530589 = 31530768
Showing the first eight; more decompositions exist.
