Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681294, here are decompositions:

3 + 8681291 = 8681294
7 + 8681287 = 8681294
31 + 8681263 = 8681294
43 + 8681251 = 8681294
73 + 8681221 = 8681294
103 + 8681191 = 8681294
163 + 8681131 = 8681294
373 + 8680921 = 8681294

Showing the first eight; more decompositions exist.
