Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593744, here are decompositions:

  • 23 + 31593721 = 31593744
  • 41 + 31593703 = 31593744
  • 97 + 31593647 = 31593744
  • 101 + 31593643 = 31593744
  • 103 + 31593641 = 31593744
  • 113 + 31593631 = 31593744
  • 131 + 31593613 = 31593744
  • 137 + 31593607 = 31593744

Showing the first eight; more decompositions exist.
