Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978178, here are decompositions:

31 + 4294978147 = 4294978178
97 + 4294978081 = 4294978178
151 + 4294978027 = 4294978178
157 + 4294978021 = 4294978178
331 + 4294977847 = 4294978178
409 + 4294977769 = 4294978178
607 + 4294977571 = 4294978178
619 + 4294977559 = 4294978178

Showing the first eight; more decompositions exist.
