Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4816, here are decompositions:

  • 3 + 4813 = 4816
  • 17 + 4799 = 4816
  • 23 + 4793 = 4816
  • 29 + 4787 = 4816
  • 83 + 4733 = 4816
  • 113 + 4703 = 4816
  • 137 + 4679 = 4816
  • 167 + 4649 = 4816

Showing the first eight; more decompositions exist.
