Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490154, here are decompositions:

101 + 2147490053 = 2147490154
197 + 2147489957 = 2147490154
281 + 2147489873 = 2147490154
311 + 2147489843 = 2147490154
503 + 2147489651 = 2147490154
617 + 2147489537 = 2147490154
857 + 2147489297 = 2147490154
863 + 2147489291 = 2147490154

Showing the first eight; more decompositions exist.
