Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487066, here are decompositions:

7 + 2147487059 = 2147487066
17 + 2147487049 = 2147487066
37 + 2147487029 = 2147487066
97 + 2147486969 = 2147487066
139 + 2147486927 = 2147487066
157 + 2147486909 = 2147487066
223 + 2147486843 = 2147487066
239 + 2147486827 = 2147487066

Showing the first eight; more decompositions exist.
