Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601720, here are decompositions:

  • 17 + 33601703 = 33601720
  • 23 + 33601697 = 33601720
  • 41 + 33601679 = 33601720
  • 71 + 33601649 = 33601720
  • 137 + 33601583 = 33601720
  • 167 + 33601553 = 33601720
  • 233 + 33601487 = 33601720
  • 311 + 33601409 = 33601720

Showing the first eight; more decompositions exist.
