Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469690, here are decompositions:

  • 11 + 2147469679 = 2147469690
  • 31 + 2147469659 = 2147469690
  • 53 + 2147469637 = 2147469690
  • 61 + 2147469629 = 2147469690
  • 71 + 2147469619 = 2147469690
  • 97 + 2147469593 = 2147469690
  • 137 + 2147469553 = 2147469690
  • 199 + 2147469491 = 2147469690

Showing the first eight; more decompositions exist.
