Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561968, here are decompositions:

19 + 33561949 = 33561968
151 + 33561817 = 33561968
199 + 33561769 = 33561968
397 + 33561571 = 33561968
409 + 33561559 = 33561968
499 + 33561469 = 33561968
607 + 33561361 = 33561968
787 + 33561181 = 33561968

Showing the first eight; more decompositions exist.
