Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681356, here are decompositions:

113 + 8681243 = 8681356
149 + 8681207 = 8681356
179 + 8681177 = 8681356
197 + 8681159 = 8681356
227 + 8681129 = 8681356
239 + 8681117 = 8681356
347 + 8681009 = 8681356
353 + 8681003 = 8681356

Showing the first eight; more decompositions exist.
