Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681008, here are decompositions:

5 + 8681003 = 8681008
101 + 8680907 = 8681008
107 + 8680901 = 8681008
137 + 8680871 = 8681008
197 + 8680811 = 8681008
227 + 8680781 = 8681008
239 + 8680769 = 8681008
311 + 8680697 = 8681008

Showing the first eight; more decompositions exist.
