Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613222, here are decompositions:

11 + 8613211 = 8613222
41 + 8613181 = 8613222
61 + 8613161 = 8613222
73 + 8613149 = 8613222
131 + 8613091 = 8613222
179 + 8613043 = 8613222
181 + 8613041 = 8613222
239 + 8612983 = 8613222

Showing the first eight; more decompositions exist.
