Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974728, here are decompositions:

211 + 4294974517 = 4294974728
271 + 4294974457 = 4294974728
277 + 4294974451 = 4294974728
367 + 4294974361 = 4294974728
397 + 4294974331 = 4294974728
739 + 4294973989 = 4294974728
829 + 4294973899 = 4294974728
859 + 4294973869 = 4294974728

Showing the first eight; more decompositions exist.
