Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487274, here are decompositions:

5 + 2147487269 = 2147487274
47 + 2147487227 = 2147487274
71 + 2147487203 = 2147487274
197 + 2147487077 = 2147487274
293 + 2147486981 = 2147487274
347 + 2147486927 = 2147487274
431 + 2147486843 = 2147487274
563 + 2147486711 = 2147487274

Showing the first eight; more decompositions exist.
