Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521428, here are decompositions:

11 + 33521417 = 33521428
107 + 33521321 = 33521428
191 + 33521237 = 33521428
251 + 33521177 = 33521428
257 + 33521171 = 33521428
389 + 33521039 = 33521428
419 + 33521009 = 33521428
449 + 33520979 = 33521428

Showing the first eight; more decompositions exist.
