Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616238, here are decompositions:

17 + 8616221 = 8616238
41 + 8616197 = 8616238
89 + 8616149 = 8616238
107 + 8616131 = 8616238
149 + 8616089 = 8616238
167 + 8616071 = 8616238
227 + 8616011 = 8616238
347 + 8615891 = 8616238

Showing the first eight; more decompositions exist.
