Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530080, here are decompositions:

71 + 33530009 = 33530080
173 + 33529907 = 33530080
179 + 33529901 = 33530080
257 + 33529823 = 33530080
293 + 33529787 = 33530080
359 + 33529721 = 33530080
509 + 33529571 = 33530080
641 + 33529439 = 33530080

Showing the first eight; more decompositions exist.
