Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563988, here are decompositions:

5 + 33563983 = 33563988
61 + 33563927 = 33563988
97 + 33563891 = 33563988
109 + 33563879 = 33563988
149 + 33563839 = 33563988
151 + 33563837 = 33563988
167 + 33563821 = 33563988
179 + 33563809 = 33563988

Showing the first eight; more decompositions exist.
