Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499946, here are decompositions:

  • 23 + 2147499923 = 2147499946
  • 29 + 2147499917 = 2147499946
  • 83 + 2147499863 = 2147499946
  • 239 + 2147499707 = 2147499946
  • 467 + 2147499479 = 2147499946
  • 509 + 2147499437 = 2147499946
  • 653 + 2147499293 = 2147499946
  • 827 + 2147499119 = 2147499946

Showing the first eight; more decompositions exist.
