Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987006, here are decompositions:

17 + 986989 = 987006
23 + 986983 = 987006
43 + 986963 = 987006
47 + 986959 = 987006
73 + 986933 = 987006
79 + 986927 = 987006
103 + 986903 = 987006
149 + 986857 = 987006

Showing the first eight; more decompositions exist.
