Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681404, here are decompositions:

3 + 8681401 = 8681404
41 + 8681363 = 8681404
47 + 8681357 = 8681404
113 + 8681291 = 8681404
191 + 8681213 = 8681404
197 + 8681207 = 8681404
227 + 8681177 = 8681404
293 + 8681111 = 8681404

Showing the first eight; more decompositions exist.
