Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3218, here are decompositions:

  • 31 + 3187 = 3218
  • 37 + 3181 = 3218
  • 97 + 3121 = 3218
  • 109 + 3109 = 3218
  • 139 + 3079 = 3218
  • 151 + 3067 = 3218
  • 157 + 3061 = 3218
  • 181 + 3037 = 3218

Showing the first eight; more decompositions exist.
