Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19994, here are decompositions:

3 + 19991 = 19994
31 + 19963 = 19994
67 + 19927 = 19994
103 + 19891 = 19994
127 + 19867 = 19994
151 + 19843 = 19994
181 + 19813 = 19994
193 + 19801 = 19994

Showing the first eight; more decompositions exist.
