Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19948, here are decompositions:

11 + 19937 = 19948
29 + 19919 = 19948
59 + 19889 = 19948
107 + 19841 = 19948
197 + 19751 = 19948
239 + 19709 = 19948
251 + 19697 = 19948
389 + 19559 = 19948

Showing the first eight; more decompositions exist.
