Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30018, here are decompositions:

5 + 30013 = 30018
7 + 30011 = 30018
29 + 29989 = 30018
59 + 29959 = 30018
71 + 29947 = 30018
97 + 29921 = 30018
101 + 29917 = 30018
137 + 29881 = 30018

Showing the first eight; more decompositions exist.
