Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487924, here are decompositions:

17 + 2147487907 = 2147487924
53 + 2147487871 = 2147487924
97 + 2147487827 = 2147487924
107 + 2147487817 = 2147487924
151 + 2147487773 = 2147487924
167 + 2147487757 = 2147487924
173 + 2147487751 = 2147487924
223 + 2147487701 = 2147487924

Showing the first eight; more decompositions exist.
