Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497916, here are decompositions:

  • 199 + 2147497717 = 2147497916
  • 409 + 2147497507 = 2147497916
  • 457 + 2147497459 = 2147497916
  • 523 + 2147497393 = 2147497916
  • 673 + 2147497243 = 2147497916
  • 877 + 2147497039 = 2147497916
  • 919 + 2147496997 = 2147497916
  • 937 + 2147496979 = 2147497916

Showing the first eight; more decompositions exist.
