Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561378, here are decompositions:

17 + 33561361 = 33561378
107 + 33561271 = 33561378
181 + 33561197 = 33561378
197 + 33561181 = 33561378
239 + 33561139 = 33561378
311 + 33561067 = 33561378
359 + 33561019 = 33561378
379 + 33560999 = 33561378

Showing the first eight; more decompositions exist.
