Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702398, here are decompositions:

11 + 8702387 = 8702398
71 + 8702327 = 8702398
167 + 8702231 = 8702398
191 + 8702207 = 8702398
239 + 8702159 = 8702398
347 + 8702051 = 8702398
389 + 8702009 = 8702398
401 + 8701997 = 8702398

Showing the first eight; more decompositions exist.
