Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489958, here are decompositions:

11 + 2147489947 = 2147489958
17 + 2147489941 = 2147489958
41 + 2147489917 = 2147489958
59 + 2147489899 = 2147489958
109 + 2147489849 = 2147489958
137 + 2147489821 = 2147489958
139 + 2147489819 = 2147489958
241 + 2147489717 = 2147489958

Showing the first eight; more decompositions exist.
