Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648388, here are decompositions:

  • 17 + 8648371 = 8648388
  • 19 + 8648369 = 8648388
  • 41 + 8648347 = 8648388
  • 71 + 8648317 = 8648388
  • 137 + 8648251 = 8648388
  • 149 + 8648239 = 8648388
  • 167 + 8648221 = 8648388
  • 197 + 8648191 = 8648388

Showing the first eight; more decompositions exist.
