Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530072, here are decompositions:

13 + 33530059 = 33530072
151 + 33529921 = 33530072
211 + 33529861 = 33530072
283 + 33529789 = 33530072
463 + 33529609 = 33530072
571 + 33529501 = 33530072
859 + 33529213 = 33530072
1231 + 33528841 = 33530072

Showing the first eight; more decompositions exist.
