Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521472, here are decompositions:

11 + 33521461 = 33521472
41 + 33521431 = 33521472
71 + 33521401 = 33521472
79 + 33521393 = 33521472
151 + 33521321 = 33521472
251 + 33521221 = 33521472
293 + 33521179 = 33521472
331 + 33521141 = 33521472

Showing the first eight; more decompositions exist.
