Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497766, here are decompositions:

  • 67 + 2147497699 = 2147497766
  • 103 + 2147497663 = 2147497766
  • 277 + 2147497489 = 2147497766
  • 307 + 2147497459 = 2147497766
  • 373 + 2147497393 = 2147497766
  • 523 + 2147497243 = 2147497766
  • 727 + 2147497039 = 2147497766
  • 769 + 2147496997 = 2147497766

Showing the first eight; more decompositions exist.
