Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485238, here are decompositions:

37 + 2147485201 = 2147485238
97 + 2147485141 = 2147485238
181 + 2147485057 = 2147485238
277 + 2147484961 = 2147485238
487 + 2147484751 = 2147485238
541 + 2147484697 = 2147485238
739 + 2147484499 = 2147485238
907 + 2147484331 = 2147485238

Showing the first eight; more decompositions exist.
