Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681304, here are decompositions:

13 + 8681291 = 8681304
17 + 8681287 = 8681304
41 + 8681263 = 8681304
53 + 8681251 = 8681304
61 + 8681243 = 8681304
83 + 8681221 = 8681304
97 + 8681207 = 8681304
113 + 8681191 = 8681304

Showing the first eight; more decompositions exist.
