Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605980, here are decompositions:

17 + 8605963 = 8605980
41 + 8605939 = 8605980
67 + 8605913 = 8605980
107 + 8605873 = 8605980
109 + 8605871 = 8605980
127 + 8605853 = 8605980
137 + 8605843 = 8605980
151 + 8605829 = 8605980

Showing the first eight; more decompositions exist.
