Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486958, here are decompositions:

31 + 2147486927 = 2147486958
79 + 2147486879 = 2147486958
101 + 2147486857 = 2147486958
107 + 2147486851 = 2147486958
109 + 2147486849 = 2147486958
131 + 2147486827 = 2147486958
139 + 2147486819 = 2147486958
167 + 2147486791 = 2147486958

Showing the first eight; more decompositions exist.
