Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718584, here are decompositions:

  • 3 + 8718581 = 8718584
  • 13 + 8718571 = 8718584
  • 97 + 8718487 = 8718584
  • 157 + 8718427 = 8718584
  • 241 + 8718343 = 8718584
  • 271 + 8718313 = 8718584
  • 283 + 8718301 = 8718584
  • 307 + 8718277 = 8718584

Showing the first eight; more decompositions exist.
