Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30028, here are decompositions:

17 + 30011 = 30028
101 + 29927 = 30028
107 + 29921 = 30028
149 + 29879 = 30028
191 + 29837 = 30028
239 + 29789 = 30028
269 + 29759 = 30028
311 + 29717 = 30028

Showing the first eight; more decompositions exist.
