Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702230, here are decompositions:

23 + 8702207 = 8702230
41 + 8702189 = 8702230
71 + 8702159 = 8702230
137 + 8702093 = 8702230
167 + 8702063 = 8702230
179 + 8702051 = 8702230
233 + 8701997 = 8702230
239 + 8701991 = 8702230

Showing the first eight; more decompositions exist.
