Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554240, here are decompositions:

  • 19 + 33554221 = 33554240
  • 73 + 33554167 = 33554240
  • 103 + 33554137 = 33554240
  • 157 + 33554083 = 33554240
  • 163 + 33554077 = 33554240
  • 229 + 33554011 = 33554240
  • 241 + 33553999 = 33554240
  • 271 + 33553969 = 33554240

Showing the first eight; more decompositions exist.
