Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30042, here are decompositions:

13 + 30029 = 30042
29 + 30013 = 30042
31 + 30011 = 30042
53 + 29989 = 30042
59 + 29983 = 30042
83 + 29959 = 30042
163 + 29879 = 30042
179 + 29863 = 30042

Showing the first eight; more decompositions exist.
