Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527696, here are decompositions:

  • 7 + 31527689 = 31527696
  • 19 + 31527677 = 31527696
  • 37 + 31527659 = 31527696
  • 113 + 31527583 = 31527696
  • 127 + 31527569 = 31527696
  • 163 + 31527533 = 31527696
  • 173 + 31527523 = 31527696
  • 197 + 31527499 = 31527696

Showing the first eight; more decompositions exist.
