Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967938, here are decompositions:

47 + 4294967891 = 4294967938
71 + 4294967867 = 4294967938
179 + 4294967759 = 4294967938
251 + 4294967687 = 4294967938
257 + 4294967681 = 4294967938
311 + 4294967627 = 4294967938
389 + 4294967549 = 4294967938
461 + 4294967477 = 4294967938

Showing the first eight; more decompositions exist.
