Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521824, here are decompositions:

3 + 33521821 = 33521824
41 + 33521783 = 33521824
71 + 33521753 = 33521824
113 + 33521711 = 33521824
131 + 33521693 = 33521824
293 + 33521531 = 33521824
353 + 33521471 = 33521824
431 + 33521393 = 33521824

Showing the first eight; more decompositions exist.
