Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629788, here are decompositions:

17 + 8629771 = 8629788
107 + 8629681 = 8629788
109 + 8629679 = 8629788
127 + 8629661 = 8629788
137 + 8629651 = 8629788
151 + 8629637 = 8629788
191 + 8629597 = 8629788
227 + 8629561 = 8629788

Showing the first eight; more decompositions exist.
