Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561288, here are decompositions:

17 + 33561271 = 33561288
97 + 33561191 = 33561288
107 + 33561181 = 33561288
127 + 33561161 = 33561288
149 + 33561139 = 33561288
199 + 33561089 = 33561288
269 + 33561019 = 33561288
281 + 33561007 = 33561288

Showing the first eight; more decompositions exist.
