Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702148, here are decompositions:

11 + 8702137 = 8702148
17 + 8702131 = 8702148
41 + 8702107 = 8702148
97 + 8702051 = 8702148
139 + 8702009 = 8702148
149 + 8701999 = 8702148
151 + 8701997 = 8702148
157 + 8701991 = 8702148

Showing the first eight; more decompositions exist.
