Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488966, here are decompositions:

47 + 2147488919 = 2147488966
53 + 2147488913 = 2147488966
59 + 2147488907 = 2147488966
107 + 2147488859 = 2147488966
173 + 2147488793 = 2147488966
239 + 2147488727 = 2147488966
347 + 2147488619 = 2147488966
353 + 2147488613 = 2147488966

Showing the first eight; more decompositions exist.
