Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718810, here are decompositions:

  • 7 + 8718803 = 8718810
  • 11 + 8718799 = 8718810
  • 13 + 8718797 = 8718810
  • 17 + 8718793 = 8718810
  • 31 + 8718779 = 8718810
  • 53 + 8718757 = 8718810
  • 73 + 8718737 = 8718810
  • 83 + 8718727 = 8718810

Showing the first eight; more decompositions exist.
