Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557408, here are decompositions:

67 + 33557341 = 33557408
151 + 33557257 = 33557408
211 + 33557197 = 33557408
277 + 33557131 = 33557408
307 + 33557101 = 33557408
331 + 33557077 = 33557408
397 + 33557011 = 33557408
439 + 33556969 = 33557408

Showing the first eight; more decompositions exist.
