Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663400, here are decompositions:

  • 43 + 8663357 = 8663400
  • 89 + 8663311 = 8663400
  • 127 + 8663273 = 8663400
  • 139 + 8663261 = 8663400
  • 191 + 8663209 = 8663400
  • 281 + 8663119 = 8663400
  • 283 + 8663117 = 8663400
  • 307 + 8663093 = 8663400

Showing the first eight; more decompositions exist.
