Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535936, here are decompositions:

  • 109 + 31535827 = 31535936
  • 127 + 31535809 = 31535936
  • 139 + 31535797 = 31535936
  • 433 + 31535503 = 31535936
  • 673 + 31535263 = 31535936
  • 709 + 31535227 = 31535936
  • 823 + 31535113 = 31535936
  • 829 + 31535107 = 31535936

Showing the first eight; more decompositions exist.
