Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716220, here are decompositions:

3 + 8716217 = 8716220
13 + 8716207 = 8716220
61 + 8716159 = 8716220
151 + 8716069 = 8716220
157 + 8716063 = 8716220
181 + 8716039 = 8716220
193 + 8716027 = 8716220
199 + 8716021 = 8716220

Showing the first eight; more decompositions exist.
