Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673218, here are decompositions:

  • 19 + 8673199 = 8673218
  • 31 + 8673187 = 8673218
  • 61 + 8673157 = 8673218
  • 97 + 8673121 = 8673218
  • 109 + 8673109 = 8673218
  • 181 + 8673037 = 8673218
  • 199 + 8673019 = 8673218
  • 271 + 8672947 = 8673218

Showing the first eight; more decompositions exist.
