Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681162, here are decompositions:

3 + 8681159 = 8681162
31 + 8681131 = 8681162
73 + 8681089 = 8681162
103 + 8681059 = 8681162
211 + 8680951 = 8681162
223 + 8680939 = 8681162
241 + 8680921 = 8681162
349 + 8680813 = 8681162

Showing the first eight; more decompositions exist.
