Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20198, here are decompositions:

37 + 20161 = 20198
97 + 20101 = 20198
109 + 20089 = 20198
127 + 20071 = 20198
151 + 20047 = 20198
271 + 19927 = 20198
307 + 19891 = 20198
331 + 19867 = 20198

Showing the first eight; more decompositions exist.
