Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19942, here are decompositions:

5 + 19937 = 19942
23 + 19919 = 19942
29 + 19913 = 19942
53 + 19889 = 19942
89 + 19853 = 19942
101 + 19841 = 19942
149 + 19793 = 19942
179 + 19763 = 19942

Showing the first eight; more decompositions exist.
