Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3286, here are decompositions:

  • 29 + 3257 = 3286
  • 83 + 3203 = 3286
  • 149 + 3137 = 3286
  • 167 + 3119 = 3286
  • 197 + 3089 = 3286
  • 263 + 3023 = 3286
  • 317 + 2969 = 3286
  • 347 + 2939 = 3286

Showing the first eight; more decompositions exist.
