Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546938, here are decompositions:

  • 29 + 31546909 = 31546938
  • 47 + 31546891 = 31546938
  • 107 + 31546831 = 31546938
  • 131 + 31546807 = 31546938
  • 139 + 31546799 = 31546938
  • 149 + 31546789 = 31546938
  • 179 + 31546759 = 31546938
  • 197 + 31546741 = 31546938

Showing the first eight; more decompositions exist.
