Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597978, here are decompositions:

19 + 33597959 = 33597978
41 + 33597937 = 33597978
101 + 33597877 = 33597978
109 + 33597869 = 33597978
131 + 33597847 = 33597978
137 + 33597841 = 33597978
151 + 33597827 = 33597978
157 + 33597821 = 33597978

Showing the first eight; more decompositions exist.
