Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688256, here are decompositions:

  • 47 + 8688209 = 8688256
  • 53 + 8688203 = 8688256
  • 89 + 8688167 = 8688256
  • 113 + 8688143 = 8688256
  • 173 + 8688083 = 8688256
  • 179 + 8688077 = 8688256
  • 197 + 8688059 = 8688256
  • 263 + 8687993 = 8688256

Showing the first eight; more decompositions exist.
