Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978238, here are decompositions:

7 + 4294978231 = 4294978238
37 + 4294978201 = 4294978238
151 + 4294978087 = 4294978238
157 + 4294978081 = 4294978238
181 + 4294978057 = 4294978238
211 + 4294978027 = 4294978238
277 + 4294977961 = 4294978238
379 + 4294977859 = 4294978238

Showing the first eight; more decompositions exist.
