Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987638, here are decompositions:

17 + 4294987621 = 4294987638
31 + 4294987607 = 4294987638
59 + 4294987579 = 4294987638
211 + 4294987427 = 4294987638
251 + 4294987387 = 4294987638
281 + 4294987357 = 4294987638
307 + 4294987331 = 4294987638
349 + 4294987289 = 4294987638

Showing the first eight; more decompositions exist.
