Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651028, here are decompositions:

11 + 8651017 = 8651028
19 + 8651009 = 8651028
31 + 8650997 = 8651028
47 + 8650981 = 8651028
101 + 8650927 = 8651028
109 + 8650919 = 8651028
131 + 8650897 = 8651028
149 + 8650879 = 8651028

Showing the first eight; more decompositions exist.
