Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23982, here are decompositions:

5 + 23977 = 23982
11 + 23971 = 23982
53 + 23929 = 23982
71 + 23911 = 23982
73 + 23909 = 23982
83 + 23899 = 23982
89 + 23893 = 23982
103 + 23879 = 23982

Showing the first eight; more decompositions exist.
