Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19950, here are decompositions:

13 + 19937 = 19950
23 + 19927 = 19950
31 + 19919 = 19950
37 + 19913 = 19950
59 + 19891 = 19950
61 + 19889 = 19950
83 + 19867 = 19950
89 + 19861 = 19950

Showing the first eight; more decompositions exist.
