Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526656, here are decompositions:

  • 23 + 31526633 = 31526656
  • 53 + 31526603 = 31526656
  • 167 + 31526489 = 31526656
  • 179 + 31526477 = 31526656
  • 233 + 31526423 = 31526656
  • 269 + 31526387 = 31526656
  • 383 + 31526273 = 31526656
  • 443 + 31526213 = 31526656

Showing the first eight; more decompositions exist.
