Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489494, here are decompositions:

11 + 2147489483 = 2147489494
53 + 2147489441 = 2147489494
71 + 2147489423 = 2147489494
197 + 2147489297 = 2147489494
251 + 2147489243 = 2147489494
587 + 2147488907 = 2147489494
701 + 2147488793 = 2147489494
743 + 2147488751 = 2147489494

Showing the first eight; more decompositions exist.
