Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16662, here are decompositions:

  • 5 + 16657 = 16662
  • 11 + 16651 = 16662
  • 13 + 16649 = 16662
  • 29 + 16633 = 16662
  • 31 + 16631 = 16662
  • 43 + 16619 = 16662
  • 59 + 16603 = 16662
  • 89 + 16573 = 16662

Showing the first eight; more decompositions exist.
