Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497808, here are decompositions:

  • 37 + 2147497771 = 2147497808
  • 109 + 2147497699 = 2147497808
  • 349 + 2147497459 = 2147497808
  • 397 + 2147497411 = 2147497808
  • 487 + 2147497321 = 2147497808
  • 571 + 2147497237 = 2147497808
  • 607 + 2147497201 = 2147497808
  • 727 + 2147497081 = 2147497808

Showing the first eight; more decompositions exist.
