Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521442, here are decompositions:

5 + 33521437 = 33521442
11 + 33521431 = 33521442
41 + 33521401 = 33521442
223 + 33521219 = 33521442
263 + 33521179 = 33521442
271 + 33521171 = 33521442
359 + 33521083 = 33521442
421 + 33521021 = 33521442

Showing the first eight; more decompositions exist.
