Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489930, here are decompositions:

13 + 2147489917 = 2147489930
31 + 2147489899 = 2147489930
109 + 2147489821 = 2147489930
277 + 2147489653 = 2147489930
457 + 2147489473 = 2147489930
631 + 2147489299 = 2147489930
727 + 2147489203 = 2147489930
787 + 2147489143 = 2147489930

Showing the first eight; more decompositions exist.
