Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702170, here are decompositions:

11 + 8702159 = 8702170
107 + 8702063 = 8702170
173 + 8701997 = 8702170
179 + 8701991 = 8702170
263 + 8701907 = 8702170
293 + 8701877 = 8702170
317 + 8701853 = 8702170
359 + 8701811 = 8702170

Showing the first eight; more decompositions exist.
