Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986994, here are decompositions:

5 + 986989 = 986994
11 + 986983 = 986994
13 + 986981 = 986994
31 + 986963 = 986994
53 + 986941 = 986994
61 + 986933 = 986994
67 + 986927 = 986994
137 + 986857 = 986994

Showing the first eight; more decompositions exist.
