Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681316, here are decompositions:

5 + 8681311 = 8681316
29 + 8681287 = 8681316
53 + 8681263 = 8681316
73 + 8681243 = 8681316
103 + 8681213 = 8681316
109 + 8681207 = 8681316
139 + 8681177 = 8681316
157 + 8681159 = 8681316

Showing the first eight; more decompositions exist.
