Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147383566, here are decompositions:

  • 47 + 2147383519 = 2147383566
  • 59 + 2147383507 = 2147383566
  • 103 + 2147383463 = 2147383566
  • 197 + 2147383369 = 2147383566
  • 239 + 2147383327 = 2147383566
  • 283 + 2147383283 = 2147383566
  • 373 + 2147383193 = 2147383566
  • 389 + 2147383177 = 2147383566

Showing the first eight; more decompositions exist.
