Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647994, here are decompositions:

  • 31 + 8647963 = 8647994
  • 67 + 8647927 = 8647994
  • 97 + 8647897 = 8647994
  • 193 + 8647801 = 8647994
  • 211 + 8647783 = 8647994
  • 241 + 8647753 = 8647994
  • 283 + 8647711 = 8647994
  • 337 + 8647657 = 8647994

Showing the first eight; more decompositions exist.
