Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987958, here are decompositions:

17 + 987941 = 987958
29 + 987929 = 987958
47 + 987911 = 987958
89 + 987869 = 987958
107 + 987851 = 987958
137 + 987821 = 987958
149 + 987809 = 987958
359 + 987599 = 987958

Showing the first eight; more decompositions exist.
