Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497814, here are decompositions:

  • 43 + 2147497771 = 2147497814
  • 97 + 2147497717 = 2147497814
  • 151 + 2147497663 = 2147497814
  • 307 + 2147497507 = 2147497814
  • 367 + 2147497447 = 2147497814
  • 421 + 2147497393 = 2147497814
  • 571 + 2147497243 = 2147497814
  • 577 + 2147497237 = 2147497814

Showing the first eight; more decompositions exist.
