Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987078, here are decompositions:

11 + 987067 = 987078
17 + 987061 = 987078
89 + 986989 = 987078
97 + 986981 = 987078
137 + 986941 = 987078
149 + 986929 = 987078
151 + 986927 = 987078
227 + 986851 = 987078

Showing the first eight; more decompositions exist.
