Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715216, here are decompositions:

7 + 8715209 = 8715216
23 + 8715193 = 8715216
73 + 8715143 = 8715216
109 + 8715107 = 8715216
113 + 8715103 = 8715216
137 + 8715079 = 8715216
157 + 8715059 = 8715216
193 + 8715023 = 8715216

Showing the first eight; more decompositions exist.
