Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651124, here are decompositions:

5 + 8651119 = 8651124
7 + 8651117 = 8651124
61 + 8651063 = 8651124
73 + 8651051 = 8651124
107 + 8651017 = 8651124
127 + 8650997 = 8651124
197 + 8650927 = 8651124
227 + 8650897 = 8651124

Showing the first eight; more decompositions exist.
