Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987982, here are decompositions:

3 + 987979 = 987982
11 + 987971 = 987982
41 + 987941 = 987982
53 + 987929 = 987982
71 + 987911 = 987982
113 + 987869 = 987982
131 + 987851 = 987982
173 + 987809 = 987982

Showing the first eight; more decompositions exist.
