Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978166, here are decompositions:

19 + 4294978147 = 4294978166
43 + 4294978123 = 4294978166
79 + 4294978087 = 4294978166
109 + 4294978057 = 4294978166
139 + 4294978027 = 4294978166
163 + 4294978003 = 4294978166
223 + 4294977943 = 4294978166
307 + 4294977859 = 4294978166

Showing the first eight; more decompositions exist.
