Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491158, here are decompositions:

19 + 2147491139 = 2147491158
31 + 2147491127 = 2147491158
47 + 2147491111 = 2147491158
67 + 2147491091 = 2147491158
89 + 2147491069 = 2147491158
97 + 2147491061 = 2147491158
139 + 2147491019 = 2147491158
151 + 2147491007 = 2147491158

Showing the first eight; more decompositions exist.
