Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489460, here are decompositions:

19 + 2147489441 = 2147489460
23 + 2147489437 = 2147489460
37 + 2147489423 = 2147489460
59 + 2147489401 = 2147489460
113 + 2147489347 = 2147489460
163 + 2147489297 = 2147489460
197 + 2147489263 = 2147489460
257 + 2147489203 = 2147489460

Showing the first eight; more decompositions exist.
