Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13662, here are decompositions:

  • 13 + 13649 = 13662
  • 29 + 13633 = 13662
  • 43 + 13619 = 13662
  • 71 + 13591 = 13662
  • 109 + 13553 = 13662
  • 139 + 13523 = 13662
  • 149 + 13513 = 13662
  • 163 + 13499 = 13662

Showing the first eight; more decompositions exist.
