Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533372, here are decompositions:

  • 29 + 31533343 = 31533372
  • 103 + 31533269 = 31533372
  • 113 + 31533259 = 31533372
  • 163 + 31533209 = 31533372
  • 181 + 31533191 = 31533372
  • 223 + 31533149 = 31533372
  • 229 + 31533143 = 31533372
  • 239 + 31533133 = 31533372

Showing the first eight; more decompositions exist.
