Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543072, here are decompositions:

  • 5 + 33543067 = 33543072
  • 11 + 33543061 = 33543072
  • 23 + 33543049 = 33543072
  • 41 + 33543031 = 33543072
  • 53 + 33543019 = 33543072
  • 89 + 33542983 = 33543072
  • 109 + 33542963 = 33543072
  • 271 + 33542801 = 33543072

Showing the first eight; more decompositions exist.
