Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497946, here are decompositions:

  • 3 + 2147497943 = 2147497946
  • 7 + 2147497939 = 2147497946
  • 229 + 2147497717 = 2147497946
  • 283 + 2147497663 = 2147497946
  • 439 + 2147497507 = 2147497946
  • 457 + 2147497489 = 2147497946
  • 487 + 2147497459 = 2147497946
  • 499 + 2147497447 = 2147497946

Showing the first eight; more decompositions exist.
