Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536224, here are decompositions:

  • 37 + 31536187 = 31536224
  • 127 + 31536097 = 31536224
  • 163 + 31536061 = 31536224
  • 241 + 31535983 = 31536224
  • 277 + 31535947 = 31536224
  • 283 + 31535941 = 31536224
  • 397 + 31535827 = 31536224
  • 631 + 31535593 = 31536224

Showing the first eight; more decompositions exist.
