Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738320, here are decompositions:

  • 47 + 8738273 = 8738320
  • 89 + 8738231 = 8738320
  • 191 + 8738129 = 8738320
  • 197 + 8738123 = 8738320
  • 233 + 8738087 = 8738320
  • 449 + 8737871 = 8738320
  • 491 + 8737829 = 8738320
  • 557 + 8737763 = 8738320

Showing the first eight; more decompositions exist.
