Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497724, here are decompositions:

  • 7 + 2147497717 = 2147497724
  • 61 + 2147497663 = 2147497724
  • 277 + 2147497447 = 2147497724
  • 313 + 2147497411 = 2147497724
  • 331 + 2147497393 = 2147497724
  • 487 + 2147497237 = 2147497724
  • 523 + 2147497201 = 2147497724
  • 643 + 2147497081 = 2147497724

Showing the first eight; more decompositions exist.
