Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509834, here are decompositions:

  • 17 + 31509817 = 31509834
  • 43 + 31509791 = 31509834
  • 53 + 31509781 = 31509834
  • 61 + 31509773 = 31509834
  • 71 + 31509763 = 31509834
  • 73 + 31509761 = 31509834
  • 137 + 31509697 = 31509834
  • 151 + 31509683 = 31509834

Showing the first eight; more decompositions exist.
