Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518160, here are decompositions:

  • 19 + 33518141 = 33518160
  • 23 + 33518137 = 33518160
  • 29 + 33518131 = 33518160
  • 41 + 33518119 = 33518160
  • 79 + 33518081 = 33518160
  • 113 + 33518047 = 33518160
  • 131 + 33518029 = 33518160
  • 139 + 33518021 = 33518160

Showing the first eight; more decompositions exist.
