Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605240, here are decompositions:

3 + 8605237 = 8605240
11 + 8605229 = 8605240
23 + 8605217 = 8605240
29 + 8605211 = 8605240
53 + 8605187 = 8605240
71 + 8605169 = 8605240
179 + 8605061 = 8605240
239 + 8605001 = 8605240

Showing the first eight; more decompositions exist.
