Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533072, here are decompositions:

43 + 33533029 = 33533072
103 + 33532969 = 33533072
109 + 33532963 = 33533072
151 + 33532921 = 33533072
193 + 33532879 = 33533072
211 + 33532861 = 33533072
241 + 33532831 = 33533072
271 + 33532801 = 33533072

Showing the first eight; more decompositions exist.
