Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985998, here are decompositions:

5 + 985993 = 985998
7 + 985991 = 985998
17 + 985981 = 985998
19 + 985979 = 985998
29 + 985969 = 985998
47 + 985951 = 985998
61 + 985937 = 985998
127 + 985871 = 985998

Showing the first eight; more decompositions exist.
