Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486490, here are decompositions:

31 + 2147486459 = 2147486490
59 + 2147486431 = 2147486490
67 + 2147486423 = 2147486490
103 + 2147486387 = 2147486490
151 + 2147486339 = 2147486490
173 + 2147486317 = 2147486490
179 + 2147486311 = 2147486490
197 + 2147486293 = 2147486490

Showing the first eight; more decompositions exist.
