Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465786, here are decompositions:

  • 5 + 31465781 = 31465786
  • 29 + 31465757 = 31465786
  • 59 + 31465727 = 31465786
  • 89 + 31465697 = 31465786
  • 113 + 31465673 = 31465786
  • 137 + 31465649 = 31465786
  • 167 + 31465619 = 31465786
  • 239 + 31465547 = 31465786

Showing the first eight; more decompositions exist.
