Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681022, here are decompositions:

13 + 8681009 = 8681022
19 + 8681003 = 8681022
29 + 8680993 = 8681022
71 + 8680951 = 8681022
83 + 8680939 = 8681022
101 + 8680921 = 8681022
113 + 8680909 = 8681022
151 + 8680871 = 8681022

Showing the first eight; more decompositions exist.
