Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528010, here are decompositions:

  • 13 + 31527997 = 31528010
  • 43 + 31527967 = 31528010
  • 79 + 31527931 = 31528010
  • 97 + 31527913 = 31528010
  • 181 + 31527829 = 31528010
  • 193 + 31527817 = 31528010
  • 223 + 31527787 = 31528010
  • 229 + 31527781 = 31528010

Showing the first eight; more decompositions exist.
