Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639360, here are decompositions:

13 + 8639347 = 8639360
61 + 8639299 = 8639360
97 + 8639263 = 8639360
109 + 8639251 = 8639360
199 + 8639161 = 8639360
211 + 8639149 = 8639360
229 + 8639131 = 8639360
241 + 8639119 = 8639360

Showing the first eight; more decompositions exist.
