Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15894, here are decompositions:

  • 5 + 15889 = 15894
  • 7 + 15887 = 15894
  • 13 + 15881 = 15894
  • 17 + 15877 = 15894
  • 71 + 15823 = 15894
  • 97 + 15797 = 15894
  • 103 + 15791 = 15894
  • 107 + 15787 = 15894

Showing the first eight; more decompositions exist.
