Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616228, here are decompositions:

7 + 8616221 = 8616228
11 + 8616217 = 8616228
29 + 8616199 = 8616228
31 + 8616197 = 8616228
41 + 8616187 = 8616228
59 + 8616169 = 8616228
79 + 8616149 = 8616228
97 + 8616131 = 8616228

Showing the first eight; more decompositions exist.
