Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681298, here are decompositions:

7 + 8681291 = 8681298
11 + 8681287 = 8681298
47 + 8681251 = 8681298
107 + 8681191 = 8681298
139 + 8681159 = 8681298
167 + 8681131 = 8681298
181 + 8681117 = 8681298
239 + 8681059 = 8681298

Showing the first eight; more decompositions exist.
