Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644800, here are decompositions:

  • 19 + 8644781 = 8644800
  • 29 + 8644771 = 8644800
  • 71 + 8644729 = 8644800
  • 97 + 8644703 = 8644800
  • 139 + 8644661 = 8644800
  • 149 + 8644651 = 8644800
  • 167 + 8644633 = 8644800
  • 191 + 8644609 = 8644800

Showing the first eight; more decompositions exist.
