Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715156, here are decompositions:

5 + 8715151 = 8715156
13 + 8715143 = 8715156
53 + 8715103 = 8715156
97 + 8715059 = 8715156
127 + 8715029 = 8715156
137 + 8715019 = 8715156
167 + 8714989 = 8715156
173 + 8714983 = 8715156

Showing the first eight; more decompositions exist.
