Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500578, here are decompositions:

17 + 2147500561 = 2147500578
19 + 2147500559 = 2147500578
71 + 2147500507 = 2147500578
79 + 2147500499 = 2147500578
227 + 2147500351 = 2147500578
239 + 2147500339 = 2147500578
277 + 2147500301 = 2147500578
281 + 2147500297 = 2147500578

Showing the first eight; more decompositions exist.
