Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681694, here are decompositions:

31 + 8681663 = 8681694
71 + 8681623 = 8681694
107 + 8681587 = 8681694
127 + 8681567 = 8681694
181 + 8681513 = 8681694
191 + 8681503 = 8681694
211 + 8681483 = 8681694
227 + 8681467 = 8681694

Showing the first eight; more decompositions exist.
