Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608712, here are decompositions:

  • 263 + 31608449 = 31608712
  • 449 + 31608263 = 31608712
  • 563 + 31608149 = 31608712
  • 683 + 31608029 = 31608712
  • 743 + 31607969 = 31608712
  • 809 + 31607903 = 31608712
  • 881 + 31607831 = 31608712
  • 929 + 31607783 = 31608712

Showing the first eight; more decompositions exist.
