Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625916, here are decompositions:

  • 5 + 31625911 = 31625916
  • 67 + 31625849 = 31625916
  • 73 + 31625843 = 31625916
  • 97 + 31625819 = 31625916
  • 109 + 31625807 = 31625916
  • 137 + 31625779 = 31625916
  • 139 + 31625777 = 31625916
  • 149 + 31625767 = 31625916

Showing the first eight; more decompositions exist.
