Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489914, here are decompositions:

5 + 2147489909 = 2147489914
41 + 2147489873 = 2147489914
71 + 2147489843 = 2147489914
197 + 2147489717 = 2147489914
263 + 2147489651 = 2147489914
431 + 2147489483 = 2147489914
491 + 2147489423 = 2147489914
617 + 2147489297 = 2147489914

Showing the first eight; more decompositions exist.
