Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16842, here are decompositions:

  • 11 + 16831 = 16842
  • 13 + 16829 = 16842
  • 19 + 16823 = 16842
  • 31 + 16811 = 16842
  • 79 + 16763 = 16842
  • 83 + 16759 = 16842
  • 101 + 16741 = 16842
  • 113 + 16729 = 16842

Showing the first eight; more decompositions exist.
