Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702210, here are decompositions:

3 + 8702207 = 8702210
31 + 8702179 = 8702210
37 + 8702173 = 8702210
61 + 8702149 = 8702210
73 + 8702137 = 8702210
79 + 8702131 = 8702210
103 + 8702107 = 8702210
211 + 8701999 = 8702210

Showing the first eight; more decompositions exist.
