Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617340, here are decompositions:

7 + 8617333 = 8617340
13 + 8617327 = 8617340
79 + 8617261 = 8617340
103 + 8617237 = 8617340
139 + 8617201 = 8617340
163 + 8617177 = 8617340
211 + 8617129 = 8617340
349 + 8616991 = 8617340

Showing the first eight; more decompositions exist.
