Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597990, here are decompositions:

31 + 33597959 = 33597990
47 + 33597943 = 33597990
53 + 33597937 = 33597990
61 + 33597929 = 33597990
67 + 33597923 = 33597990
113 + 33597877 = 33597990
131 + 33597859 = 33597990
137 + 33597853 = 33597990

Showing the first eight; more decompositions exist.
