Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596750, here are decompositions:

  • 7 + 31596743 = 31596750
  • 37 + 31596713 = 31596750
  • 41 + 31596709 = 31596750
  • 43 + 31596707 = 31596750
  • 71 + 31596679 = 31596750
  • 79 + 31596671 = 31596750
  • 89 + 31596661 = 31596750
  • 113 + 31596637 = 31596750

Showing the first eight; more decompositions exist.
