Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615154, here are decompositions:

5 + 8615149 = 8615154
17 + 8615137 = 8615154
71 + 8615083 = 8615154
103 + 8615051 = 8615154
137 + 8615017 = 8615154
167 + 8614987 = 8615154
181 + 8614973 = 8615154
241 + 8614913 = 8615154

Showing the first eight; more decompositions exist.
