Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489008, here are decompositions:

11 + 2147488997 = 2147489008
89 + 2147488919 = 2147489008
101 + 2147488907 = 2147489008
149 + 2147488859 = 2147489008
257 + 2147488751 = 2147489008
281 + 2147488727 = 2147489008
317 + 2147488691 = 2147489008
389 + 2147488619 = 2147489008

Showing the first eight; more decompositions exist.
