Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484774, here are decompositions:

23 + 2147484751 = 2147484774
41 + 2147484733 = 2147484774
53 + 2147484721 = 2147484774
157 + 2147484617 = 2147484774
163 + 2147484611 = 2147484774
173 + 2147484601 = 2147484774
233 + 2147484541 = 2147484774
257 + 2147484517 = 2147484774

Showing the first eight; more decompositions exist.
