Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16816, here are decompositions:

  • 5 + 16811 = 16816
  • 29 + 16787 = 16816
  • 53 + 16763 = 16816
  • 113 + 16703 = 16816
  • 167 + 16649 = 16816
  • 197 + 16619 = 16816
  • 263 + 16553 = 16816
  • 269 + 16547 = 16816

Showing the first eight; more decompositions exist.
