Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624936, here are decompositions:

  • 29 + 31624907 = 31624936
  • 107 + 31624829 = 31624936
  • 137 + 31624799 = 31624936
  • 173 + 31624763 = 31624936
  • 197 + 31624739 = 31624936
  • 263 + 31624673 = 31624936
  • 293 + 31624643 = 31624936
  • 389 + 31624547 = 31624936

Showing the first eight; more decompositions exist.
