Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987026, here are decompositions:

3 + 987023 = 987026
13 + 987013 = 987026
37 + 986989 = 987026
43 + 986983 = 987026
67 + 986959 = 987026
97 + 986929 = 987026
277 + 986749 = 987026
307 + 986719 = 987026

Showing the first eight; more decompositions exist.
