Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26686, here are decompositions:

  • 3 + 26683 = 26686
  • 5 + 26681 = 26686
  • 17 + 26669 = 26686
  • 53 + 26633 = 26686
  • 59 + 26627 = 26686
  • 89 + 26597 = 26686
  • 113 + 26573 = 26686
  • 173 + 26513 = 26686

Showing the first eight; more decompositions exist.
