Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688238, here are decompositions:

  • 17 + 8688221 = 8688238
  • 29 + 8688209 = 8688238
  • 71 + 8688167 = 8688238
  • 137 + 8688101 = 8688238
  • 179 + 8688059 = 8688238
  • 227 + 8688011 = 8688238
  • 257 + 8687981 = 8688238
  • 347 + 8687891 = 8688238

Showing the first eight; more decompositions exist.
