Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17718, here are decompositions:

  • 5 + 17713 = 17718
  • 11 + 17707 = 17718
  • 37 + 17681 = 17718
  • 59 + 17659 = 17718
  • 61 + 17657 = 17718
  • 109 + 17609 = 17718
  • 137 + 17581 = 17718
  • 139 + 17579 = 17718

Showing the first eight; more decompositions exist.
