Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681704, here are decompositions:

11 + 8681693 = 8681704
41 + 8681663 = 8681704
137 + 8681567 = 8681704
191 + 8681513 = 8681704
197 + 8681507 = 8681704
257 + 8681447 = 8681704
347 + 8681357 = 8681704
461 + 8681243 = 8681704

Showing the first eight; more decompositions exist.
