Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597872, here are decompositions:

3 + 33597869 = 33597872
13 + 33597859 = 33597872
19 + 33597853 = 33597872
31 + 33597841 = 33597872
163 + 33597709 = 33597872
181 + 33597691 = 33597872
223 + 33597649 = 33597872
421 + 33597451 = 33597872

Showing the first eight; more decompositions exist.
