Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986940, here are decompositions:

7 + 986933 = 986940
11 + 986929 = 986940
13 + 986927 = 986940
37 + 986903 = 986940
83 + 986857 = 986940
89 + 986851 = 986940
103 + 986837 = 986940
127 + 986813 = 986940

Showing the first eight; more decompositions exist.
