Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19958, here are decompositions:

31 + 19927 = 19958
67 + 19891 = 19958
97 + 19861 = 19958
139 + 19819 = 19958
157 + 19801 = 19958
181 + 19777 = 19958
199 + 19759 = 19958
241 + 19717 = 19958

Showing the first eight; more decompositions exist.
