Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668078, here are decompositions:

5 + 8668073 = 8668078
11 + 8668067 = 8668078
17 + 8668061 = 8668078
47 + 8668031 = 8668078
149 + 8667929 = 8668078
179 + 8667899 = 8668078
257 + 8667821 = 8668078
269 + 8667809 = 8668078

Showing the first eight; more decompositions exist.
