Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663424, here are decompositions:

  • 23 + 8663401 = 8663424
  • 67 + 8663357 = 8663424
  • 113 + 8663311 = 8663424
  • 151 + 8663273 = 8663424
  • 163 + 8663261 = 8663424
  • 271 + 8663153 = 8663424
  • 307 + 8663117 = 8663424
  • 331 + 8663093 = 8663424

Showing the first eight; more decompositions exist.
