Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497776, here are decompositions:

  • 5 + 2147497771 = 2147497776
  • 7 + 2147497769 = 2147497776
  • 19 + 2147497757 = 2147497776
  • 43 + 2147497733 = 2147497776
  • 59 + 2147497717 = 2147497776
  • 79 + 2147497697 = 2147497776
  • 113 + 2147497663 = 2147497776
  • 269 + 2147497507 = 2147497776

Showing the first eight; more decompositions exist.
