Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30834, here are decompositions:

5 + 30829 = 30834
17 + 30817 = 30834
31 + 30803 = 30834
53 + 30781 = 30834
61 + 30773 = 30834
71 + 30763 = 30834
107 + 30727 = 30834
127 + 30707 = 30834

Showing the first eight; more decompositions exist.
