Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716720, here are decompositions:

  • 11 + 8716709 = 8716720
  • 17 + 8716703 = 8716720
  • 29 + 8716691 = 8716720
  • 41 + 8716679 = 8716720
  • 59 + 8716661 = 8716720
  • 101 + 8716619 = 8716720
  • 107 + 8716613 = 8716720
  • 137 + 8716583 = 8716720

Showing the first eight; more decompositions exist.
