Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605518, here are decompositions:

7 + 8605511 = 8605518
17 + 8605501 = 8605518
37 + 8605481 = 8605518
71 + 8605447 = 8605518
107 + 8605411 = 8605518
139 + 8605379 = 8605518
149 + 8605369 = 8605518
157 + 8605361 = 8605518

Showing the first eight; more decompositions exist.
