Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601728, here are decompositions:

  • 5 + 33601723 = 33601728
  • 31 + 33601697 = 33601728
  • 71 + 33601657 = 33601728
  • 79 + 33601649 = 33601728
  • 101 + 33601627 = 33601728
  • 179 + 33601549 = 33601728
  • 227 + 33601501 = 33601728
  • 241 + 33601487 = 33601728

Showing the first eight; more decompositions exist.
