Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605660, here are decompositions:

23 + 8605637 = 8605660
53 + 8605607 = 8605660
59 + 8605601 = 8605660
83 + 8605577 = 8605660
131 + 8605529 = 8605660
149 + 8605511 = 8605660
179 + 8605481 = 8605660
191 + 8605469 = 8605660

Showing the first eight; more decompositions exist.
