Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521400, here are decompositions:

  • 7 + 33521393 = 33521400
  • 79 + 33521321 = 33521400
  • 163 + 33521237 = 33521400
  • 179 + 33521221 = 33521400
  • 181 + 33521219 = 33521400
  • 223 + 33521177 = 33521400
  • 229 + 33521171 = 33521400
  • 313 + 33521087 = 33521400

Showing the first eight; more decompositions exist.
