Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483868, here are decompositions:

11 + 2147483857 = 2147483868
239 + 2147483629 = 2147483868
281 + 2147483587 = 2147483868
379 + 2147483489 = 2147483868
599 + 2147483269 = 2147483868
619 + 2147483249 = 2147483868
631 + 2147483237 = 2147483868
809 + 2147483059 = 2147483868

Showing the first eight; more decompositions exist.
