Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472934, here are decompositions:

11 + 2147472923 = 2147472934
17 + 2147472917 = 2147472934
41 + 2147472893 = 2147472934
71 + 2147472863 = 2147472934
137 + 2147472797 = 2147472934
251 + 2147472683 = 2147472934
317 + 2147472617 = 2147472934
443 + 2147472491 = 2147472934

Showing the first eight; more decompositions exist.
