Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681374, here are decompositions:

5 + 8681369 = 8681374
11 + 8681363 = 8681374
17 + 8681357 = 8681374
83 + 8681291 = 8681374
131 + 8681243 = 8681374
167 + 8681207 = 8681374
197 + 8681177 = 8681374
257 + 8681117 = 8681374

Showing the first eight; more decompositions exist.
