Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681674, here are decompositions:

5 + 8681669 = 8681674
11 + 8681663 = 8681674
107 + 8681567 = 8681674
167 + 8681507 = 8681674
191 + 8681483 = 8681674
227 + 8681447 = 8681674
311 + 8681363 = 8681674
317 + 8681357 = 8681674

Showing the first eight; more decompositions exist.
