Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978078, here are decompositions:

11 + 4294978067 = 4294978078
89 + 4294977989 = 4294978078
179 + 4294977899 = 4294978078
197 + 4294977881 = 4294978078
239 + 4294977839 = 4294978078
317 + 4294977761 = 4294978078
647 + 4294977431 = 4294978078
659 + 4294977419 = 4294978078

Showing the first eight; more decompositions exist.
