Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637810, here are decompositions:

  • 19 + 8637791 = 8637810
  • 23 + 8637787 = 8637810
  • 31 + 8637779 = 8637810
  • 61 + 8637749 = 8637810
  • 109 + 8637701 = 8637810
  • 113 + 8637697 = 8637810
  • 173 + 8637637 = 8637810
  • 191 + 8637619 = 8637810

Showing the first eight; more decompositions exist.
