Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681124, here are decompositions:

7 + 8681117 = 8681124
13 + 8681111 = 8681124
47 + 8681077 = 8681124
103 + 8681021 = 8681124
131 + 8680993 = 8681124
173 + 8680951 = 8681124
223 + 8680901 = 8681124
311 + 8680813 = 8681124

Showing the first eight; more decompositions exist.
