Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681142, here are decompositions:

11 + 8681131 = 8681142
13 + 8681129 = 8681142
31 + 8681111 = 8681142
53 + 8681089 = 8681142
83 + 8681059 = 8681142
139 + 8681003 = 8681142
149 + 8680993 = 8681142
191 + 8680951 = 8681142

Showing the first eight; more decompositions exist.
