Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978240, here are decompositions:

17 + 4294978223 = 4294978240
29 + 4294978211 = 4294978240
71 + 4294978169 = 4294978240
83 + 4294978157 = 4294978240
107 + 4294978133 = 4294978240
149 + 4294978091 = 4294978240
173 + 4294978067 = 4294978240
251 + 4294977989 = 4294978240

Showing the first eight; more decompositions exist.
