Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715208, here are decompositions:

17 + 8715191 = 8715208
101 + 8715107 = 8715208
149 + 8715059 = 8715208
167 + 8715041 = 8715208
179 + 8715029 = 8715208
197 + 8715011 = 8715208
251 + 8714957 = 8715208
419 + 8714789 = 8715208

Showing the first eight; more decompositions exist.
