Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681224, here are decompositions:

3 + 8681221 = 8681224
11 + 8681213 = 8681224
17 + 8681207 = 8681224
47 + 8681177 = 8681224
107 + 8681117 = 8681224
113 + 8681111 = 8681224
317 + 8680907 = 8681224
353 + 8680871 = 8681224

Showing the first eight; more decompositions exist.
