Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478128, here are decompositions:

79 + 2147478049 = 2147478128
139 + 2147477989 = 2147478128
277 + 2147477851 = 2147478128
661 + 2147477467 = 2147478128
709 + 2147477419 = 2147478128
919 + 2147477209 = 2147478128
937 + 2147477191 = 2147478128
1021 + 2147477107 = 2147478128

Showing the first eight; more decompositions exist.
