Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605572, here are decompositions:

5 + 8605567 = 8605572
11 + 8605561 = 8605572
29 + 8605543 = 8605572
43 + 8605529 = 8605572
61 + 8605511 = 8605572
71 + 8605501 = 8605572
103 + 8605469 = 8605572
109 + 8605463 = 8605572

Showing the first eight; more decompositions exist.
