Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718618, here are decompositions:

  • 17 + 8718601 = 8718618
  • 37 + 8718581 = 8718618
  • 47 + 8718571 = 8718618
  • 79 + 8718539 = 8718618
  • 127 + 8718491 = 8718618
  • 131 + 8718487 = 8718618
  • 149 + 8718469 = 8718618
  • 157 + 8718461 = 8718618

Showing the first eight; more decompositions exist.
