Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19962, here are decompositions:

13 + 19949 = 19962
43 + 19919 = 19962
71 + 19891 = 19962
73 + 19889 = 19962
101 + 19861 = 19962
109 + 19853 = 19962
149 + 19813 = 19962
199 + 19763 = 19962

Showing the first eight; more decompositions exist.
