Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978280, here are decompositions:

31 + 4294978249 = 4294978280
79 + 4294978201 = 4294978280
157 + 4294978123 = 4294978280
193 + 4294978087 = 4294978280
199 + 4294978081 = 4294978280
223 + 4294978057 = 4294978280
277 + 4294978003 = 4294978280
337 + 4294977943 = 4294978280

Showing the first eight; more decompositions exist.
