Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470936, here are decompositions:

  • 19 + 31470917 = 31470936
  • 23 + 31470913 = 31470936
  • 47 + 31470889 = 31470936
  • 67 + 31470869 = 31470936
  • 73 + 31470863 = 31470936
  • 83 + 31470853 = 31470936
  • 89 + 31470847 = 31470936
  • 103 + 31470833 = 31470936

Showing the first eight; more decompositions exist.
