Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716212, here are decompositions:

5 + 8716207 = 8716212
31 + 8716181 = 8716212
53 + 8716159 = 8716212
61 + 8716151 = 8716212
103 + 8716109 = 8716212
149 + 8716063 = 8716212
151 + 8716061 = 8716212
173 + 8716039 = 8716212

Showing the first eight; more decompositions exist.
