Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521568, here are decompositions:

19 + 33521549 = 33521568
29 + 33521539 = 33521568
37 + 33521531 = 33521568
97 + 33521471 = 33521568
107 + 33521461 = 33521568
131 + 33521437 = 33521568
137 + 33521431 = 33521568
151 + 33521417 = 33521568

Showing the first eight; more decompositions exist.
