Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475916, here are decompositions:

  • 17 + 2147475899 = 2147475916
  • 263 + 2147475653 = 2147475916
  • 353 + 2147475563 = 2147475916
  • 419 + 2147475497 = 2147475916
  • 503 + 2147475413 = 2147475916
  • 569 + 2147475347 = 2147475916
  • 647 + 2147475269 = 2147475916
  • 659 + 2147475257 = 2147475916

Showing the first eight; more decompositions exist.
