Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491788, here are decompositions:

7 + 2147491781 = 2147491788
31 + 2147491757 = 2147491788
89 + 2147491699 = 2147491788
97 + 2147491691 = 2147491788
179 + 2147491609 = 2147491788
181 + 2147491607 = 2147491788
191 + 2147491597 = 2147491788
229 + 2147491559 = 2147491788

Showing the first eight; more decompositions exist.
