Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957638, here are decompositions:

29 + 4294957609 = 4294957638
199 + 4294957439 = 4294957638
239 + 4294957399 = 4294957638
241 + 4294957397 = 4294957638
269 + 4294957369 = 4294957638
331 + 4294957307 = 4294957638
431 + 4294957207 = 4294957638
449 + 4294957189 = 4294957638

Showing the first eight; more decompositions exist.
