Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624388, here are decompositions:

  • 5 + 8624383 = 8624388
  • 61 + 8624327 = 8624388
  • 137 + 8624251 = 8624388
  • 139 + 8624249 = 8624388
  • 151 + 8624237 = 8624388
  • 167 + 8624221 = 8624388
  • 197 + 8624191 = 8624388
  • 211 + 8624177 = 8624388

Showing the first eight; more decompositions exist.
