Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561400, here are decompositions:

11 + 33561389 = 33561400
113 + 33561287 = 33561400
137 + 33561263 = 33561400
227 + 33561173 = 33561400
239 + 33561161 = 33561400
311 + 33561089 = 33561400
347 + 33561053 = 33561400
401 + 33560999 = 33561400

Showing the first eight; more decompositions exist.
