Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681988, here are decompositions:

11 + 8681977 = 8681988
19 + 8681969 = 8681988
31 + 8681957 = 8681988
47 + 8681941 = 8681988
89 + 8681899 = 8681988
131 + 8681857 = 8681988
137 + 8681851 = 8681988
151 + 8681837 = 8681988

Showing the first eight; more decompositions exist.
