Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659210, here are decompositions:

3 + 8659207 = 8659210
29 + 8659181 = 8659210
89 + 8659121 = 8659210
113 + 8659097 = 8659210
149 + 8659061 = 8659210
167 + 8659043 = 8659210
173 + 8659037 = 8659210
191 + 8659019 = 8659210

Showing the first eight; more decompositions exist.
