Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506640, here are decompositions:

  • 17 + 33506623 = 33506640
  • 23 + 33506617 = 33506640
  • 43 + 33506597 = 33506640
  • 53 + 33506587 = 33506640
  • 59 + 33506581 = 33506640
  • 61 + 33506579 = 33506640
  • 67 + 33506573 = 33506640
  • 71 + 33506569 = 33506640

Showing the first eight; more decompositions exist.
