Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707864, here are decompositions:

  • 3 + 8707861 = 8707864
  • 23 + 8707841 = 8707864
  • 47 + 8707817 = 8707864
  • 71 + 8707793 = 8707864
  • 83 + 8707781 = 8707864
  • 101 + 8707763 = 8707864
  • 167 + 8707697 = 8707864
  • 233 + 8707631 = 8707864

Showing the first eight; more decompositions exist.
