Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613872, here are decompositions:

11 + 33613861 = 33613872
13 + 33613859 = 33613872
23 + 33613849 = 33613872
29 + 33613843 = 33613872
31 + 33613841 = 33613872
43 + 33613829 = 33613872
109 + 33613763 = 33613872
191 + 33613681 = 33613872

Showing the first eight; more decompositions exist.
