Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978878, here are decompositions:

5 + 4294978873 = 4294978878
11 + 4294978867 = 4294978878
67 + 4294978811 = 4294978878
79 + 4294978799 = 4294978878
97 + 4294978781 = 4294978878
101 + 4294978777 = 4294978878
149 + 4294978729 = 4294978878
199 + 4294978679 = 4294978878

Showing the first eight; more decompositions exist.
