Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485128, here are decompositions:

7 + 2147485121 = 2147485128
31 + 2147485097 = 2147485128
71 + 2147485057 = 2147485128
137 + 2147484991 = 2147485128
167 + 2147484961 = 2147485128
179 + 2147484949 = 2147485128
199 + 2147484929 = 2147485128
251 + 2147484877 = 2147485128

Showing the first eight; more decompositions exist.
