Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680940, here are decompositions:

19 + 8680921 = 8680940
31 + 8680909 = 8680940
127 + 8680813 = 8680940
139 + 8680801 = 8680940
199 + 8680741 = 8680940
223 + 8680717 = 8680940
241 + 8680699 = 8680940
271 + 8680669 = 8680940

Showing the first eight; more decompositions exist.
