Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681398, here are decompositions:

29 + 8681369 = 8681398
41 + 8681357 = 8681398
107 + 8681291 = 8681398
191 + 8681207 = 8681398
239 + 8681159 = 8681398
269 + 8681129 = 8681398
281 + 8681117 = 8681398
389 + 8681009 = 8681398

Showing the first eight; more decompositions exist.
