Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475170, here are decompositions:

  • 67 + 2147475103 = 2147475170
  • 109 + 2147475061 = 2147475170
  • 223 + 2147474947 = 2147475170
  • 241 + 2147474929 = 2147475170
  • 283 + 2147474887 = 2147475170
  • 367 + 2147474803 = 2147475170
  • 619 + 2147474551 = 2147475170
  • 691 + 2147474479 = 2147475170

Showing the first eight; more decompositions exist.
