Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473156, here are decompositions:

5 + 2147473151 = 2147473156
29 + 2147473127 = 2147473156
107 + 2147473049 = 2147473156
197 + 2147472959 = 2147473156
233 + 2147472923 = 2147473156
239 + 2147472917 = 2147473156
263 + 2147472893 = 2147473156
293 + 2147472863 = 2147473156

Showing the first eight; more decompositions exist.
