Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533246, here are decompositions:

  • 37 + 31533209 = 31533246
  • 79 + 31533167 = 31533246
  • 97 + 31533149 = 31533246
  • 103 + 31533143 = 31533246
  • 113 + 31533133 = 31533246
  • 127 + 31533119 = 31533246
  • 149 + 31533097 = 31533246
  • 233 + 31533013 = 31533246

Showing the first eight; more decompositions exist.
