Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22000, here are decompositions:

  • 3 + 21997 = 22000
  • 23 + 21977 = 22000
  • 71 + 21929 = 22000
  • 89 + 21911 = 22000
  • 107 + 21893 = 22000
  • 137 + 21863 = 22000
  • 149 + 21851 = 22000
  • 179 + 21821 = 22000

Showing the first eight; more decompositions exist.
