Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526328, here are decompositions:

  • 11 + 31526317 = 31526328
  • 47 + 31526281 = 31526328
  • 89 + 31526239 = 31526328
  • 101 + 31526227 = 31526328
  • 107 + 31526221 = 31526328
  • 131 + 31526197 = 31526328
  • 137 + 31526191 = 31526328
  • 139 + 31526189 = 31526328

Showing the first eight; more decompositions exist.
