Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521988, here are decompositions:

7 + 33521981 = 33521988
29 + 33521959 = 33521988
61 + 33521927 = 33521988
67 + 33521921 = 33521988
127 + 33521861 = 33521988
167 + 33521821 = 33521988
191 + 33521797 = 33521988
229 + 33521759 = 33521988

Showing the first eight; more decompositions exist.
