Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485172, here are decompositions:

31 + 2147485141 = 2147485172
181 + 2147484991 = 2147485172
211 + 2147484961 = 2147485172
223 + 2147484949 = 2147485172
421 + 2147484751 = 2147485172
439 + 2147484733 = 2147485172
571 + 2147484601 = 2147485172
619 + 2147484553 = 2147485172

Showing the first eight; more decompositions exist.
