Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700216, here are decompositions:

23 + 8700193 = 8700216
47 + 8700169 = 8700216
103 + 8700113 = 8700216
137 + 8700079 = 8700216
157 + 8700059 = 8700216
179 + 8700037 = 8700216
197 + 8700019 = 8700216
223 + 8699993 = 8700216

Showing the first eight; more decompositions exist.
