Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497736, here are decompositions:

  • 3 + 2147497733 = 2147497736
  • 19 + 2147497717 = 2147497736
  • 37 + 2147497699 = 2147497736
  • 73 + 2147497663 = 2147497736
  • 229 + 2147497507 = 2147497736
  • 277 + 2147497459 = 2147497736
  • 499 + 2147497237 = 2147497736
  • 739 + 2147496997 = 2147497736

Showing the first eight; more decompositions exist.
