Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528026, here are decompositions:

  • 7 + 31528019 = 31528026
  • 29 + 31527997 = 31528026
  • 59 + 31527967 = 31528026
  • 113 + 31527913 = 31528026
  • 139 + 31527887 = 31528026
  • 197 + 31527829 = 31528026
  • 199 + 31527827 = 31528026
  • 239 + 31527787 = 31528026

Showing the first eight; more decompositions exist.
