Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487968, here are decompositions:

37 + 2147487931 = 2147487968
61 + 2147487907 = 2147487968
97 + 2147487871 = 2147487968
139 + 2147487829 = 2147487968
151 + 2147487817 = 2147487968
211 + 2147487757 = 2147487968
277 + 2147487691 = 2147487968
331 + 2147487637 = 2147487968

Showing the first eight; more decompositions exist.
