Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30852, here are decompositions:

11 + 30841 = 30852
13 + 30839 = 30852
23 + 30829 = 30852
43 + 30809 = 30852
71 + 30781 = 30852
79 + 30773 = 30852
89 + 30763 = 30852
139 + 30713 = 30852

Showing the first eight; more decompositions exist.
