Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978640, here are decompositions:

13 + 4294978627 = 4294978640
151 + 4294978489 = 4294978640
241 + 4294978399 = 4294978640
307 + 4294978333 = 4294978640
313 + 4294978327 = 4294978640
331 + 4294978309 = 4294978640
409 + 4294978231 = 4294978640
439 + 4294978201 = 4294978640

Showing the first eight; more decompositions exist.
