Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646918, here are decompositions:

19 + 8646899 = 8646918
29 + 8646889 = 8646918
67 + 8646851 = 8646918
97 + 8646821 = 8646918
101 + 8646817 = 8646918
139 + 8646779 = 8646918
167 + 8646751 = 8646918
197 + 8646721 = 8646918

Showing the first eight; more decompositions exist.
