Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702178, here are decompositions:

5 + 8702173 = 8702178
19 + 8702159 = 8702178
29 + 8702149 = 8702178
41 + 8702137 = 8702178
47 + 8702131 = 8702178
71 + 8702107 = 8702178
127 + 8702051 = 8702178
179 + 8701999 = 8702178

Showing the first eight; more decompositions exist.
