Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497322, here are decompositions:

  • 23 + 31497299 = 31497322
  • 29 + 31497293 = 31497322
  • 71 + 31497251 = 31497322
  • 239 + 31497083 = 31497322
  • 251 + 31497071 = 31497322
  • 359 + 31496963 = 31497322
  • 401 + 31496921 = 31497322
  • 449 + 31496873 = 31497322

Showing the first eight; more decompositions exist.
