Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521740, here are decompositions:

11 + 33521729 = 33521740
29 + 33521711 = 33521740
47 + 33521693 = 33521740
191 + 33521549 = 33521740
257 + 33521483 = 33521740
269 + 33521471 = 33521740
347 + 33521393 = 33521740
419 + 33521321 = 33521740

Showing the first eight; more decompositions exist.
