Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616222, here are decompositions:

5 + 8616217 = 8616222
19 + 8616203 = 8616222
23 + 8616199 = 8616222
53 + 8616169 = 8616222
71 + 8616151 = 8616222
73 + 8616149 = 8616222
151 + 8616071 = 8616222
179 + 8616043 = 8616222

Showing the first eight; more decompositions exist.
