Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601518, here are decompositions:

7 + 8601511 = 8601518
19 + 8601499 = 8601518
61 + 8601457 = 8601518
97 + 8601421 = 8601518
127 + 8601391 = 8601518
157 + 8601361 = 8601518
229 + 8601289 = 8601518
241 + 8601277 = 8601518

Showing the first eight; more decompositions exist.
