Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521552, here are decompositions:

3 + 33521549 = 33521552
13 + 33521539 = 33521552
151 + 33521401 = 33521552
331 + 33521221 = 33521552
373 + 33521179 = 33521552
613 + 33520939 = 33521552
661 + 33520891 = 33521552
709 + 33520843 = 33521552

Showing the first eight; more decompositions exist.
