Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543120, here are decompositions:

  • 41 + 33543079 = 33543120
  • 53 + 33543067 = 33543120
  • 59 + 33543061 = 33543120
  • 71 + 33543049 = 33543120
  • 89 + 33543031 = 33543120
  • 101 + 33543019 = 33543120
  • 103 + 33543017 = 33543120
  • 137 + 33542983 = 33543120

Showing the first eight; more decompositions exist.
