Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491794, here are decompositions:

13 + 2147491781 = 2147491794
37 + 2147491757 = 2147491794
61 + 2147491733 = 2147491794
103 + 2147491691 = 2147491794
191 + 2147491603 = 2147491794
197 + 2147491597 = 2147491794
211 + 2147491583 = 2147491794
241 + 2147491553 = 2147491794

Showing the first eight; more decompositions exist.
