Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647700, here are decompositions:

  • 3 + 8647697 = 8647700
  • 43 + 8647657 = 8647700
  • 163 + 8647537 = 8647700
  • 199 + 8647501 = 8647700
  • 241 + 8647459 = 8647700
  • 283 + 8647417 = 8647700
  • 307 + 8647393 = 8647700
  • 331 + 8647369 = 8647700

Showing the first eight; more decompositions exist.
