Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521644, here are decompositions:

113 + 33521531 = 33521644
173 + 33521471 = 33521644
227 + 33521417 = 33521644
251 + 33521393 = 33521644
467 + 33521177 = 33521644
503 + 33521141 = 33521644
557 + 33521087 = 33521644
587 + 33521057 = 33521644

Showing the first eight; more decompositions exist.
