Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615328, here are decompositions:

5 + 8615323 = 8615328
41 + 8615287 = 8615328
61 + 8615267 = 8615328
67 + 8615261 = 8615328
97 + 8615231 = 8615328
109 + 8615219 = 8615328
131 + 8615197 = 8615328
151 + 8615177 = 8615328

Showing the first eight; more decompositions exist.
