Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681010, here are decompositions:

7 + 8681003 = 8681010
17 + 8680993 = 8681010
59 + 8680951 = 8681010
71 + 8680939 = 8681010
89 + 8680921 = 8681010
101 + 8680909 = 8681010
103 + 8680907 = 8681010
109 + 8680901 = 8681010

Showing the first eight; more decompositions exist.
