Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557988, here are decompositions:

7 + 33557981 = 33557988
47 + 33557941 = 33557988
67 + 33557921 = 33557988
71 + 33557917 = 33557988
89 + 33557899 = 33557988
97 + 33557891 = 33557988
109 + 33557879 = 33557988
151 + 33557837 = 33557988

Showing the first eight; more decompositions exist.
