Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978168, here are decompositions:

11 + 4294978157 = 4294978168
101 + 4294978067 = 4294978168
179 + 4294977989 = 4294978168
269 + 4294977899 = 4294978168
821 + 4294977347 = 4294978168
839 + 4294977329 = 4294978168
857 + 4294977311 = 4294978168
881 + 4294977287 = 4294978168

Showing the first eight; more decompositions exist.
