Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639422, here are decompositions:

  • 41 + 8639381 = 8639422
  • 59 + 8639363 = 8639422
  • 131 + 8639291 = 8639422
  • 149 + 8639273 = 8639422
  • 173 + 8639249 = 8639422
  • 251 + 8639171 = 8639422
  • 269 + 8639153 = 8639422
  • 359 + 8639063 = 8639422

Showing the first eight; more decompositions exist.
