Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530746, here are decompositions:

  • 43 + 31530703 = 31530746
  • 67 + 31530679 = 31530746
  • 97 + 31530649 = 31530746
  • 103 + 31530643 = 31530746
  • 109 + 31530637 = 31530746
  • 139 + 31530607 = 31530746
  • 157 + 31530589 = 31530746
  • 223 + 31530523 = 31530746

Showing the first eight; more decompositions exist.
