Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486508, here are decompositions:

7 + 2147486501 = 2147486508
109 + 2147486399 = 2147486508
179 + 2147486329 = 2147486508
191 + 2147486317 = 2147486508
197 + 2147486311 = 2147486508
239 + 2147486269 = 2147486508
311 + 2147486197 = 2147486508
379 + 2147486129 = 2147486508

Showing the first eight; more decompositions exist.
