Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16920, here are decompositions:

  • 17 + 16903 = 16920
  • 19 + 16901 = 16920
  • 31 + 16889 = 16920
  • 37 + 16883 = 16920
  • 41 + 16879 = 16920
  • 89 + 16831 = 16920
  • 97 + 16823 = 16920
  • 109 + 16811 = 16920

Showing the first eight; more decompositions exist.
