Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647982, here are decompositions:

  • 3 + 8647979 = 8647982
  • 19 + 8647963 = 8647982
  • 103 + 8647879 = 8647982
  • 163 + 8647819 = 8647982
  • 181 + 8647801 = 8647982
  • 199 + 8647783 = 8647982
  • 223 + 8647759 = 8647982
  • 229 + 8647753 = 8647982

Showing the first eight; more decompositions exist.
