Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616078, here are decompositions:

7 + 8616071 = 8616078
41 + 8616037 = 8616078
59 + 8616019 = 8616078
67 + 8616011 = 8616078
89 + 8615989 = 8616078
137 + 8615941 = 8616078
197 + 8615881 = 8616078
199 + 8615879 = 8616078

Showing the first eight; more decompositions exist.
