Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978390, here are decompositions:

29 + 4294978361 = 4294978390
83 + 4294978307 = 4294978390
107 + 4294978283 = 4294978390
167 + 4294978223 = 4294978390
179 + 4294978211 = 4294978390
233 + 4294978157 = 4294978390
257 + 4294978133 = 4294978390
401 + 4294977989 = 4294978390

Showing the first eight; more decompositions exist.
