Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986988, here are decompositions:

5 + 986983 = 986988
7 + 986981 = 986988
29 + 986959 = 986988
47 + 986941 = 986988
59 + 986929 = 986988
61 + 986927 = 986988
131 + 986857 = 986988
137 + 986851 = 986988

Showing the first eight; more decompositions exist.
