Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30072, here are decompositions:

13 + 30059 = 30072
43 + 30029 = 30072
59 + 30013 = 30072
61 + 30011 = 30072
83 + 29989 = 30072
89 + 29983 = 30072
113 + 29959 = 30072
151 + 29921 = 30072

Showing the first eight; more decompositions exist.
