Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526568, here are decompositions:

  • 5 + 31526563 = 31526568
  • 41 + 31526527 = 31526568
  • 71 + 31526497 = 31526568
  • 79 + 31526489 = 31526568
  • 137 + 31526431 = 31526568
  • 149 + 31526419 = 31526568
  • 179 + 31526389 = 31526568
  • 181 + 31526387 = 31526568

Showing the first eight; more decompositions exist.
