Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536020, here are decompositions:

  • 3 + 31536017 = 31536020
  • 37 + 31535983 = 31536020
  • 73 + 31535947 = 31536020
  • 79 + 31535941 = 31536020
  • 193 + 31535827 = 31536020
  • 199 + 31535821 = 31536020
  • 211 + 31535809 = 31536020
  • 223 + 31535797 = 31536020

Showing the first eight; more decompositions exist.
