Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19834, here are decompositions:

41 + 19793 = 19834
71 + 19763 = 19834
83 + 19751 = 19834
107 + 19727 = 19834
137 + 19697 = 19834
173 + 19661 = 19834
251 + 19583 = 19834
257 + 19577 = 19834

Showing the first eight; more decompositions exist.
