Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13756, here are decompositions:

  • 5 + 13751 = 13756
  • 47 + 13709 = 13756
  • 59 + 13697 = 13756
  • 107 + 13649 = 13756
  • 137 + 13619 = 13756
  • 179 + 13577 = 13756
  • 233 + 13523 = 13756
  • 257 + 13499 = 13756

Showing the first eight; more decompositions exist.
