Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681274, here are decompositions:

11 + 8681263 = 8681274
23 + 8681251 = 8681274
31 + 8681243 = 8681274
53 + 8681221 = 8681274
61 + 8681213 = 8681274
67 + 8681207 = 8681274
83 + 8681191 = 8681274
97 + 8681177 = 8681274

Showing the first eight; more decompositions exist.
