Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9966, here are decompositions:

  • 17 + 9949 = 9966
  • 37 + 9929 = 9966
  • 43 + 9923 = 9966
  • 59 + 9907 = 9966
  • 79 + 9887 = 9966
  • 83 + 9883 = 9966
  • 107 + 9859 = 9966
  • 109 + 9857 = 9966

Showing the first eight; more decompositions exist.
