Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521840, here are decompositions:

13 + 33521827 = 33521840
19 + 33521821 = 33521840
43 + 33521797 = 33521840
109 + 33521731 = 33521840
127 + 33521713 = 33521840
139 + 33521701 = 33521840
151 + 33521689 = 33521840
193 + 33521647 = 33521840

Showing the first eight; more decompositions exist.
