Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715222, here are decompositions:

13 + 8715209 = 8715222
29 + 8715193 = 8715222
31 + 8715191 = 8715222
41 + 8715181 = 8715222
71 + 8715151 = 8715222
79 + 8715143 = 8715222
163 + 8715059 = 8715222
181 + 8715041 = 8715222

Showing the first eight; more decompositions exist.
