Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718860, here are decompositions:

  • 37 + 8718823 = 8718860
  • 61 + 8718799 = 8718860
  • 67 + 8718793 = 8718860
  • 103 + 8718757 = 8718860
  • 127 + 8718733 = 8718860
  • 151 + 8718709 = 8718860
  • 211 + 8718649 = 8718860
  • 373 + 8718487 = 8718860

Showing the first eight; more decompositions exist.
