Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615208, here are decompositions:

11 + 8615197 = 8615208
31 + 8615177 = 8615208
47 + 8615161 = 8615208
59 + 8615149 = 8615208
71 + 8615137 = 8615208
109 + 8615099 = 8615208
157 + 8615051 = 8615208
191 + 8615017 = 8615208

Showing the first eight; more decompositions exist.
