Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681006, here are decompositions:

3 + 8681003 = 8681006
13 + 8680993 = 8681006
67 + 8680939 = 8681006
97 + 8680909 = 8681006
193 + 8680813 = 8681006
283 + 8680723 = 8681006
307 + 8680699 = 8681006
337 + 8680669 = 8681006

Showing the first eight; more decompositions exist.
