Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716840, here are decompositions:

  • 23 + 8716817 = 8716840
  • 71 + 8716769 = 8716840
  • 113 + 8716727 = 8716840
  • 131 + 8716709 = 8716840
  • 137 + 8716703 = 8716840
  • 149 + 8716691 = 8716840
  • 179 + 8716661 = 8716840
  • 227 + 8716613 = 8716840

Showing the first eight; more decompositions exist.
