Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 14818, here are decompositions:

  • 5 + 14813 = 14818
  • 47 + 14771 = 14818
  • 59 + 14759 = 14818
  • 71 + 14747 = 14818
  • 101 + 14717 = 14818
  • 149 + 14669 = 14818
  • 179 + 14639 = 14818
  • 191 + 14627 = 14818

Showing the first eight; more decompositions exist.
