Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597980, here are decompositions:

37 + 33597943 = 33597980
43 + 33597937 = 33597980
67 + 33597913 = 33597980
103 + 33597877 = 33597980
127 + 33597853 = 33597980
139 + 33597841 = 33597980
193 + 33597787 = 33597980
271 + 33597709 = 33597980

Showing the first eight; more decompositions exist.
