Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561432, here are decompositions:

19 + 33561413 = 33561432
43 + 33561389 = 33561432
53 + 33561379 = 33561432
71 + 33561361 = 33561432
89 + 33561343 = 33561432
239 + 33561193 = 33561432
241 + 33561191 = 33561432
251 + 33561181 = 33561432

Showing the first eight; more decompositions exist.
