Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521398, here are decompositions:

5 + 33521393 = 33521398
179 + 33521219 = 33521398
227 + 33521171 = 33521398
257 + 33521141 = 33521398
311 + 33521087 = 33521398
359 + 33521039 = 33521398
389 + 33521009 = 33521398
419 + 33520979 = 33521398

Showing the first eight; more decompositions exist.
