Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624240, here are decompositions:

  • 3 + 8624237 = 8624240
  • 19 + 8624221 = 8624240
  • 61 + 8624179 = 8624240
  • 103 + 8624137 = 8624240
  • 109 + 8624131 = 8624240
  • 139 + 8624101 = 8624240
  • 181 + 8624059 = 8624240
  • 223 + 8624017 = 8624240

Showing the first eight; more decompositions exist.
