Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681346, here are decompositions:

5 + 8681341 = 8681346
29 + 8681317 = 8681346
59 + 8681287 = 8681346
83 + 8681263 = 8681346
103 + 8681243 = 8681346
139 + 8681207 = 8681346
229 + 8681117 = 8681346
257 + 8681089 = 8681346

Showing the first eight; more decompositions exist.
