Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497566, here are decompositions:

  • 7 + 2147497559 = 2147497566
  • 43 + 2147497523 = 2147497566
  • 59 + 2147497507 = 2147497566
  • 73 + 2147497493 = 2147497566
  • 107 + 2147497459 = 2147497566
  • 163 + 2147497403 = 2147497566
  • 173 + 2147497393 = 2147497566
  • 433 + 2147497133 = 2147497566

Showing the first eight; more decompositions exist.
