Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597972, here are decompositions:

13 + 33597959 = 33597972
29 + 33597943 = 33597972
43 + 33597929 = 33597972
59 + 33597913 = 33597972
103 + 33597869 = 33597972
113 + 33597859 = 33597972
131 + 33597841 = 33597972
151 + 33597821 = 33597972

Showing the first eight; more decompositions exist.
