Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680938, here are decompositions:

17 + 8680921 = 8680938
29 + 8680909 = 8680938
31 + 8680907 = 8680938
37 + 8680901 = 8680938
67 + 8680871 = 8680938
127 + 8680811 = 8680938
137 + 8680801 = 8680938
157 + 8680781 = 8680938

Showing the first eight; more decompositions exist.
