Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11686, here are decompositions:

  • 5 + 11681 = 11686
  • 29 + 11657 = 11686
  • 53 + 11633 = 11686
  • 89 + 11597 = 11686
  • 107 + 11579 = 11686
  • 137 + 11549 = 11686
  • 167 + 11519 = 11686
  • 197 + 11489 = 11686

Showing the first eight; more decompositions exist.
