Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22816, here are decompositions:

  • 5 + 22811 = 22816
  • 29 + 22787 = 22816
  • 47 + 22769 = 22816
  • 89 + 22727 = 22816
  • 107 + 22709 = 22816
  • 137 + 22679 = 22816
  • 173 + 22643 = 22816
  • 179 + 22637 = 22816

Showing the first eight; more decompositions exist.
