Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715888, here are decompositions:

7 + 8715881 = 8715888
11 + 8715877 = 8715888
47 + 8715841 = 8715888
101 + 8715787 = 8715888
109 + 8715779 = 8715888
127 + 8715761 = 8715888
157 + 8715731 = 8715888
179 + 8715709 = 8715888

Showing the first eight; more decompositions exist.
