Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622208, here are decompositions:

  • 17 + 8622191 = 8622208
  • 71 + 8622137 = 8622208
  • 137 + 8622071 = 8622208
  • 167 + 8622041 = 8622208
  • 191 + 8622017 = 8622208
  • 197 + 8622011 = 8622208
  • 269 + 8621939 = 8622208
  • 281 + 8621927 = 8622208

Showing the first eight; more decompositions exist.
