Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618960, here are decompositions:

  • 7 + 33618953 = 33618960
  • 17 + 33618943 = 33618960
  • 41 + 33618919 = 33618960
  • 71 + 33618889 = 33618960
  • 73 + 33618887 = 33618960
  • 103 + 33618857 = 33618960
  • 107 + 33618853 = 33618960
  • 181 + 33618779 = 33618960

Showing the first eight; more decompositions exist.
