Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715388, here are decompositions:

  • 5 + 8715383 = 8715388
  • 41 + 8715347 = 8715388
  • 179 + 8715209 = 8715388
  • 197 + 8715191 = 8715388
  • 281 + 8715107 = 8715388
  • 347 + 8715041 = 8715388
  • 359 + 8715029 = 8715388
  • 431 + 8714957 = 8715388

Showing the first eight; more decompositions exist.
