Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681766, here are decompositions:

29 + 8681737 = 8681766
59 + 8681707 = 8681766
73 + 8681693 = 8681766
97 + 8681669 = 8681766
103 + 8681663 = 8681766
127 + 8681639 = 8681766
179 + 8681587 = 8681766
199 + 8681567 = 8681766

Showing the first eight; more decompositions exist.
