Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616340, here are decompositions:

3 + 8616337 = 8616340
17 + 8616323 = 8616340
41 + 8616299 = 8616340
59 + 8616281 = 8616340
137 + 8616203 = 8616340
167 + 8616173 = 8616340
191 + 8616149 = 8616340
251 + 8616089 = 8616340

Showing the first eight; more decompositions exist.
