Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978072, here are decompositions:

5 + 4294978067 = 4294978072
83 + 4294977989 = 4294978072
173 + 4294977899 = 4294978072
179 + 4294977893 = 4294978072
191 + 4294977881 = 4294978072
233 + 4294977839 = 4294978072
311 + 4294977761 = 4294978072
401 + 4294977671 = 4294978072

Showing the first eight; more decompositions exist.
