Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533738, here are decompositions:

  • 17 + 31533721 = 31533738
  • 31 + 31533707 = 31533738
  • 79 + 31533659 = 31533738
  • 97 + 31533641 = 31533738
  • 101 + 31533637 = 31533738
  • 107 + 31533631 = 31533738
  • 127 + 31533611 = 31533738
  • 139 + 31533599 = 31533738

Showing the first eight; more decompositions exist.
