Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469828, here are decompositions:

  • 5 + 2147469823 = 2147469828
  • 11 + 2147469817 = 2147469828
  • 47 + 2147469781 = 2147469828
  • 149 + 2147469679 = 2147469828
  • 191 + 2147469637 = 2147469828
  • 199 + 2147469629 = 2147469828
  • 307 + 2147469521 = 2147469828
  • 337 + 2147469491 = 2147469828

Showing the first eight; more decompositions exist.
