Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681354, here are decompositions:

13 + 8681341 = 8681354
37 + 8681317 = 8681354
43 + 8681311 = 8681354
67 + 8681287 = 8681354
103 + 8681251 = 8681354
163 + 8681191 = 8681354
223 + 8681131 = 8681354
277 + 8681077 = 8681354

Showing the first eight; more decompositions exist.
