Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597720, here are decompositions:

  • 11 + 33597709 = 33597720
  • 29 + 33597691 = 33597720
  • 43 + 33597677 = 33597720
  • 53 + 33597667 = 33597720
  • 61 + 33597659 = 33597720
  • 71 + 33597649 = 33597720
  • 73 + 33597647 = 33597720
  • 83 + 33597637 = 33597720

Showing the first eight; more decompositions exist.
