Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3220, here are decompositions:

  • 3 + 3217 = 3220
  • 11 + 3209 = 3220
  • 17 + 3203 = 3220
  • 29 + 3191 = 3220
  • 53 + 3167 = 3220
  • 83 + 3137 = 3220
  • 101 + 3119 = 3220
  • 131 + 3089 = 3220

Showing the first eight; more decompositions exist.
