Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646078, here are decompositions:

17 + 8646061 = 8646078
19 + 8646059 = 8646078
61 + 8646017 = 8646078
97 + 8645981 = 8646078
107 + 8645971 = 8646078
137 + 8645941 = 8646078
151 + 8645927 = 8646078
179 + 8645899 = 8646078

Showing the first eight; more decompositions exist.
