Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491288, here are decompositions:

11 + 2147491277 = 2147491288
71 + 2147491217 = 2147491288
149 + 2147491139 = 2147491288
197 + 2147491091 = 2147491288
227 + 2147491061 = 2147491288
251 + 2147491037 = 2147491288
269 + 2147491019 = 2147491288
281 + 2147491007 = 2147491288

Showing the first eight; more decompositions exist.
