Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536146, here are decompositions:

  • 97 + 31536049 = 31536146
  • 127 + 31536019 = 31536146
  • 163 + 31535983 = 31536146
  • 199 + 31535947 = 31536146
  • 337 + 31535809 = 31536146
  • 349 + 31535797 = 31536146
  • 643 + 31535503 = 31536146
  • 727 + 31535419 = 31536146

Showing the first eight; more decompositions exist.
