Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647922, here are decompositions:

  • 43 + 8647879 = 8647922
  • 103 + 8647819 = 8647922
  • 139 + 8647783 = 8647922
  • 163 + 8647759 = 8647922
  • 211 + 8647711 = 8647922
  • 223 + 8647699 = 8647922
  • 421 + 8647501 = 8647922
  • 463 + 8647459 = 8647922

Showing the first eight; more decompositions exist.
