Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978988, here are decompositions:

211 + 4294978777 = 4294978988
397 + 4294978591 = 4294978988
499 + 4294978489 = 4294978988
607 + 4294978381 = 4294978988
661 + 4294978327 = 4294978988
739 + 4294978249 = 4294978988
757 + 4294978231 = 4294978988
787 + 4294978201 = 4294978988

Showing the first eight; more decompositions exist.
