Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702164, here are decompositions:

5 + 8702159 = 8702164
71 + 8702093 = 8702164
101 + 8702063 = 8702164
113 + 8702051 = 8702164
167 + 8701997 = 8702164
173 + 8701991 = 8702164
257 + 8701907 = 8702164
281 + 8701883 = 8702164

Showing the first eight; more decompositions exist.
