Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465936, here are decompositions:

  • 107 + 31465829 = 31465936
  • 179 + 31465757 = 31465936
  • 239 + 31465697 = 31465936
  • 263 + 31465673 = 31465936
  • 317 + 31465619 = 31465936
  • 389 + 31465547 = 31465936
  • 647 + 31465289 = 31465936
  • 743 + 31465193 = 31465936

Showing the first eight; more decompositions exist.
