Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20258, here are decompositions:

97 + 20161 = 20258
109 + 20149 = 20258
151 + 20107 = 20258
157 + 20101 = 20258
211 + 20047 = 20258
229 + 20029 = 20258
331 + 19927 = 20258
367 + 19891 = 20258

Showing the first eight; more decompositions exist.
