Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467912, here are decompositions:

  • 41 + 2147467871 = 2147467912
  • 179 + 2147467733 = 2147467912
  • 281 + 2147467631 = 2147467912
  • 353 + 2147467559 = 2147467912
  • 419 + 2147467493 = 2147467912
  • 449 + 2147467463 = 2147467912
  • 509 + 2147467403 = 2147467912
  • 701 + 2147467211 = 2147467912

Showing the first eight; more decompositions exist.
