Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681994, here are decompositions:

5 + 8681989 = 8681994
17 + 8681977 = 8681994
37 + 8681957 = 8681994
53 + 8681941 = 8681994
71 + 8681923 = 8681994
137 + 8681857 = 8681994
157 + 8681837 = 8681994
163 + 8681831 = 8681994

Showing the first eight; more decompositions exist.
