Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536216, here are decompositions:

  • 13 + 31536203 = 31536216
  • 29 + 31536187 = 31536216
  • 163 + 31536053 = 31536216
  • 167 + 31536049 = 31536216
  • 197 + 31536019 = 31536216
  • 199 + 31536017 = 31536216
  • 233 + 31535983 = 31536216
  • 269 + 31535947 = 31536216

Showing the first eight; more decompositions exist.
