Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497524, here are decompositions:

  • 17 + 2147497507 = 2147497524
  • 31 + 2147497493 = 2147497524
  • 43 + 2147497481 = 2147497524
  • 113 + 2147497411 = 2147497524
  • 131 + 2147497393 = 2147497524
  • 163 + 2147497361 = 2147497524
  • 281 + 2147497243 = 2147497524
  • 383 + 2147497141 = 2147497524

Showing the first eight; more decompositions exist.
