Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715198, here are decompositions:

5 + 8715193 = 8715198
7 + 8715191 = 8715198
17 + 8715181 = 8715198
47 + 8715151 = 8715198
139 + 8715059 = 8715198
157 + 8715041 = 8715198
179 + 8715019 = 8715198
241 + 8714957 = 8715198

Showing the first eight; more decompositions exist.
