Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681324, here are decompositions:

7 + 8681317 = 8681324
13 + 8681311 = 8681324
37 + 8681287 = 8681324
61 + 8681263 = 8681324
73 + 8681251 = 8681324
103 + 8681221 = 8681324
193 + 8681131 = 8681324
277 + 8681047 = 8681324

Showing the first eight; more decompositions exist.
