Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988638, here are decompositions:

29 + 4294988609 = 4294988638
47 + 4294988591 = 4294988638
251 + 4294988387 = 4294988638
461 + 4294988177 = 4294988638
491 + 4294988147 = 4294988638
509 + 4294988129 = 4294988638
617 + 4294988021 = 4294988638
719 + 4294987919 = 4294988638

Showing the first eight; more decompositions exist.
