Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561988, here are decompositions:

11 + 33561977 = 33561988
29 + 33561959 = 33561988
59 + 33561929 = 33561988
71 + 33561917 = 33561988
107 + 33561881 = 33561988
137 + 33561851 = 33561988
149 + 33561839 = 33561988
269 + 33561719 = 33561988

Showing the first eight; more decompositions exist.
