Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19894, here are decompositions:

3 + 19891 = 19894
5 + 19889 = 19894
41 + 19853 = 19894
53 + 19841 = 19894
101 + 19793 = 19894
131 + 19763 = 19894
167 + 19727 = 19894
197 + 19697 = 19894

Showing the first eight; more decompositions exist.
