Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521818, here are decompositions:

59 + 33521759 = 33521818
89 + 33521729 = 33521818
107 + 33521711 = 33521818
269 + 33521549 = 33521818
347 + 33521471 = 33521818
401 + 33521417 = 33521818
599 + 33521219 = 33521818
641 + 33521177 = 33521818

Showing the first eight; more decompositions exist.
