Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615166, here are decompositions:

5 + 8615161 = 8615166
17 + 8615149 = 8615166
29 + 8615137 = 8615166
67 + 8615099 = 8615166
83 + 8615083 = 8615166
103 + 8615063 = 8615166
149 + 8615017 = 8615166
179 + 8614987 = 8615166

Showing the first eight; more decompositions exist.
