Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557970, here are decompositions:

29 + 33557941 = 33557970
53 + 33557917 = 33557970
59 + 33557911 = 33557970
71 + 33557899 = 33557970
79 + 33557891 = 33557970
163 + 33557807 = 33557970
181 + 33557789 = 33557970
233 + 33557737 = 33557970

Showing the first eight; more decompositions exist.
