Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540710, here are decompositions:

  • 11 + 31540699 = 31540710
  • 17 + 31540693 = 31540710
  • 31 + 31540679 = 31540710
  • 41 + 31540669 = 31540710
  • 53 + 31540657 = 31540710
  • 59 + 31540651 = 31540710
  • 67 + 31540643 = 31540710
  • 73 + 31540637 = 31540710

Showing the first eight; more decompositions exist.
