Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457322, here are decompositions:

  • 11 + 31457311 = 31457322
  • 19 + 31457303 = 31457322
  • 53 + 31457269 = 31457322
  • 151 + 31457171 = 31457322
  • 163 + 31457159 = 31457322
  • 173 + 31457149 = 31457322
  • 223 + 31457099 = 31457322
  • 229 + 31457093 = 31457322

Showing the first eight; more decompositions exist.
