Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30020, here are decompositions:

7 + 30013 = 30020
31 + 29989 = 30020
37 + 29983 = 30020
61 + 29959 = 30020
73 + 29947 = 30020
103 + 29917 = 30020
139 + 29881 = 30020
157 + 29863 = 30020

Showing the first eight; more decompositions exist.
