Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17982, here are decompositions:

5 + 17977 = 17982
11 + 17971 = 17982
23 + 17959 = 17982
43 + 17939 = 17982
53 + 17929 = 17982
59 + 17923 = 17982
61 + 17921 = 17982
71 + 17911 = 17982

Showing the first eight; more decompositions exist.
