Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13776, here are decompositions:

  • 13 + 13763 = 13776
  • 17 + 13759 = 13776
  • 19 + 13757 = 13776
  • 47 + 13729 = 13776
  • 53 + 13723 = 13776
  • 67 + 13709 = 13776
  • 79 + 13697 = 13776
  • 83 + 13693 = 13776

Showing the first eight; more decompositions exist.
