Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521864, here are decompositions:

3 + 33521861 = 33521864
37 + 33521827 = 33521864
43 + 33521821 = 33521864
67 + 33521797 = 33521864
151 + 33521713 = 33521864
163 + 33521701 = 33521864
241 + 33521623 = 33521864
433 + 33521431 = 33521864

Showing the first eight; more decompositions exist.
