Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618240, here are decompositions:

  • 31 + 33618209 = 33618240
  • 41 + 33618199 = 33618240
  • 67 + 33618173 = 33618240
  • 79 + 33618161 = 33618240
  • 101 + 33618139 = 33618240
  • 137 + 33618103 = 33618240
  • 211 + 33618029 = 33618240
  • 233 + 33618007 = 33618240

Showing the first eight; more decompositions exist.
