Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13936, here are decompositions:

  • 3 + 13933 = 13936
  • 5 + 13931 = 13936
  • 23 + 13913 = 13936
  • 29 + 13907 = 13936
  • 53 + 13883 = 13936
  • 59 + 13877 = 13936
  • 107 + 13829 = 13936
  • 137 + 13799 = 13936

Showing the first eight; more decompositions exist.
