Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483648, here are decompositions:

19 + 2147483629 = 2147483648
61 + 2147483587 = 2147483648
151 + 2147483497 = 2147483648
379 + 2147483269 = 2147483648
571 + 2147483077 = 2147483648
619 + 2147483029 = 2147483648
727 + 2147482921 = 2147483648
829 + 2147482819 = 2147483648

Showing the first eight; more decompositions exist.
