Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503240, here are decompositions:

  • 61 + 33503179 = 33503240
  • 79 + 33503161 = 33503240
  • 151 + 33503089 = 33503240
  • 157 + 33503083 = 33503240
  • 163 + 33503077 = 33503240
  • 181 + 33503059 = 33503240
  • 229 + 33503011 = 33503240
  • 241 + 33502999 = 33503240

Showing the first eight; more decompositions exist.
