Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643948, here are decompositions:

7 + 8643941 = 8643948
29 + 8643919 = 8643948
59 + 8643889 = 8643948
97 + 8643851 = 8643948
109 + 8643839 = 8643948
127 + 8643821 = 8643948
151 + 8643797 = 8643948
191 + 8643757 = 8643948

Showing the first eight; more decompositions exist.
