Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466966, here are decompositions:

  • 19 + 2147466947 = 2147466966
  • 23 + 2147466943 = 2147466966
  • 97 + 2147466869 = 2147466966
  • 173 + 2147466793 = 2147466966
  • 179 + 2147466787 = 2147466966
  • 283 + 2147466683 = 2147466966
  • 419 + 2147466547 = 2147466966
  • 479 + 2147466487 = 2147466966

Showing the first eight; more decompositions exist.
