Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489720, here are decompositions:

  • 7 + 33489713 = 33489720
  • 13 + 33489707 = 33489720
  • 31 + 33489689 = 33489720
  • 37 + 33489683 = 33489720
  • 67 + 33489653 = 33489720
  • 71 + 33489649 = 33489720
  • 97 + 33489623 = 33489720
  • 101 + 33489619 = 33489720

Showing the first eight; more decompositions exist.
