Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987002, here are decompositions:

13 + 986989 = 987002
19 + 986983 = 987002
43 + 986959 = 987002
61 + 986941 = 987002
73 + 986929 = 987002
151 + 986851 = 987002
223 + 986779 = 987002
283 + 986719 = 987002

Showing the first eight; more decompositions exist.
