Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472268, here are decompositions:

5 + 2147472263 = 2147472268
17 + 2147472251 = 2147472268
47 + 2147472221 = 2147472268
107 + 2147472161 = 2147472268
131 + 2147472137 = 2147472268
167 + 2147472101 = 2147472268
197 + 2147472071 = 2147472268
317 + 2147471951 = 2147472268

Showing the first eight; more decompositions exist.
