Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561424, here are decompositions:

11 + 33561413 = 33561424
137 + 33561287 = 33561424
227 + 33561197 = 33561424
233 + 33561191 = 33561424
251 + 33561173 = 33561424
263 + 33561161 = 33561424
401 + 33561023 = 33561424
683 + 33560741 = 33561424

Showing the first eight; more decompositions exist.
