Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147494530, here are decompositions:

19 + 2147494511 = 2147494530
23 + 2147494507 = 2147494530
43 + 2147494487 = 2147494530
61 + 2147494469 = 2147494530
67 + 2147494463 = 2147494530
173 + 2147494357 = 2147494530
227 + 2147494303 = 2147494530
257 + 2147494273 = 2147494530

Showing the first eight; more decompositions exist.
