Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646930, here are decompositions:

31 + 8646899 = 8646930
41 + 8646889 = 8646930
79 + 8646851 = 8646930
107 + 8646823 = 8646930
109 + 8646821 = 8646930
113 + 8646817 = 8646930
137 + 8646793 = 8646930
151 + 8646779 = 8646930

Showing the first eight; more decompositions exist.
