Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19946, here are decompositions:

19 + 19927 = 19946
79 + 19867 = 19946
103 + 19843 = 19946
127 + 19819 = 19946
193 + 19753 = 19946
229 + 19717 = 19946
337 + 19609 = 19946
349 + 19597 = 19946

Showing the first eight; more decompositions exist.
