Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676864, here are decompositions:

  • 17 + 8676847 = 8676864
  • 37 + 8676827 = 8676864
  • 43 + 8676821 = 8676864
  • 83 + 8676781 = 8676864
  • 107 + 8676757 = 8676864
  • 113 + 8676751 = 8676864
  • 173 + 8676691 = 8676864
  • 223 + 8676641 = 8676864

Showing the first eight; more decompositions exist.
