Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617888, here are decompositions:

  • 11 + 31617877 = 31617888
  • 17 + 31617871 = 31617888
  • 61 + 31617827 = 31617888
  • 131 + 31617757 = 31617888
  • 191 + 31617697 = 31617888
  • 199 + 31617689 = 31617888
  • 229 + 31617659 = 31617888
  • 257 + 31617631 = 31617888

Showing the first eight; more decompositions exist.
