Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30006, here are decompositions:

17 + 29989 = 30006
23 + 29983 = 30006
47 + 29959 = 30006
59 + 29947 = 30006
79 + 29927 = 30006
89 + 29917 = 30006
127 + 29879 = 30006
139 + 29867 = 30006

Showing the first eight; more decompositions exist.
