Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484918, here are decompositions:

41 + 2147484877 = 2147484918
67 + 2147484851 = 2147484918
97 + 2147484821 = 2147484918
127 + 2147484791 = 2147484918
167 + 2147484751 = 2147484918
197 + 2147484721 = 2147484918
239 + 2147484679 = 2147484918
277 + 2147484641 = 2147484918

Showing the first eight; more decompositions exist.
