Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972816, here are decompositions:

  • 17 + 972799 = 972816
  • 23 + 972793 = 972816
  • 29 + 972787 = 972816
  • 137 + 972679 = 972816
  • 167 + 972649 = 972816
  • 179 + 972637 = 972816
  • 193 + 972623 = 972816
  • 239 + 972577 = 972816

Showing the first eight; more decompositions exist.
