Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19934, here are decompositions:

7 + 19927 = 19934
43 + 19891 = 19934
67 + 19867 = 19934
73 + 19861 = 19934
157 + 19777 = 19934
181 + 19753 = 19934
331 + 19603 = 19934
337 + 19597 = 19934

Showing the first eight; more decompositions exist.
