Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489188, here are decompositions:

101 + 2147489087 = 2147489188
191 + 2147488997 = 2147489188
269 + 2147488919 = 2147489188
281 + 2147488907 = 2147489188
461 + 2147488727 = 2147489188
569 + 2147488619 = 2147489188
881 + 2147488307 = 2147489188
941 + 2147488247 = 2147489188

Showing the first eight; more decompositions exist.
