Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615214, here are decompositions:

17 + 8615197 = 8615214
37 + 8615177 = 8615214
53 + 8615161 = 8615214
131 + 8615083 = 8615214
151 + 8615063 = 8615214
163 + 8615051 = 8615214
197 + 8615017 = 8615214
227 + 8614987 = 8615214

Showing the first eight; more decompositions exist.
