Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651198, here are decompositions:

7 + 8651191 = 8651198
19 + 8651179 = 8651198
37 + 8651161 = 8651198
79 + 8651119 = 8651198
151 + 8651047 = 8651198
181 + 8651017 = 8651198
271 + 8650927 = 8651198
349 + 8650849 = 8651198

Showing the first eight; more decompositions exist.
