Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533400, here are decompositions:

  • 11 + 31533389 = 31533400
  • 29 + 31533371 = 31533400
  • 131 + 31533269 = 31533400
  • 191 + 31533209 = 31533400
  • 233 + 31533167 = 31533400
  • 251 + 31533149 = 31533400
  • 257 + 31533143 = 31533400
  • 281 + 31533119 = 31533400

Showing the first eight; more decompositions exist.
