Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681358, here are decompositions:

17 + 8681341 = 8681358
41 + 8681317 = 8681358
47 + 8681311 = 8681358
67 + 8681291 = 8681358
71 + 8681287 = 8681358
107 + 8681251 = 8681358
137 + 8681221 = 8681358
151 + 8681207 = 8681358

Showing the first eight; more decompositions exist.
