Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 718, here are decompositions:

  • 17 + 701 = 718
  • 41 + 677 = 718
  • 59 + 659 = 718
  • 71 + 647 = 718
  • 101 + 617 = 718
  • 131 + 587 = 718
  • 149 + 569 = 718
  • 197 + 521 = 718

Showing the first eight; more decompositions exist.
