Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16636, here are decompositions:

  • 3 + 16633 = 16636
  • 5 + 16631 = 16636
  • 17 + 16619 = 16636
  • 29 + 16607 = 16636
  • 83 + 16553 = 16636
  • 89 + 16547 = 16636
  • 107 + 16529 = 16636
  • 149 + 16487 = 16636

Showing the first eight; more decompositions exist.
