Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605540, here are decompositions:

11 + 8605529 = 8605540
29 + 8605511 = 8605540
59 + 8605481 = 8605540
71 + 8605469 = 8605540
107 + 8605433 = 8605540
137 + 8605403 = 8605540
179 + 8605361 = 8605540
233 + 8605307 = 8605540

Showing the first eight; more decompositions exist.
