Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521992, here are decompositions:

3 + 33521989 = 33521992
11 + 33521981 = 33521992
59 + 33521933 = 33521992
71 + 33521921 = 33521992
89 + 33521903 = 33521992
131 + 33521861 = 33521992
149 + 33521843 = 33521992
233 + 33521759 = 33521992

Showing the first eight; more decompositions exist.
