Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521908, here are decompositions:

5 + 33521903 = 33521908
47 + 33521861 = 33521908
149 + 33521759 = 33521908
179 + 33521729 = 33521908
197 + 33521711 = 33521908
359 + 33521549 = 33521908
491 + 33521417 = 33521908
587 + 33521321 = 33521908

Showing the first eight; more decompositions exist.
