Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978268, here are decompositions:

19 + 4294978249 = 4294978268
37 + 4294978231 = 4294978268
67 + 4294978201 = 4294978268
181 + 4294978087 = 4294978268
211 + 4294978057 = 4294978268
241 + 4294978027 = 4294978268
277 + 4294977991 = 4294978268
307 + 4294977961 = 4294978268

Showing the first eight; more decompositions exist.
