Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33565840, here are decompositions:

17 + 33565823 = 33565840
23 + 33565817 = 33565840
29 + 33565811 = 33565840
89 + 33565751 = 33565840
107 + 33565733 = 33565840
131 + 33565709 = 33565840
137 + 33565703 = 33565840
149 + 33565691 = 33565840

Showing the first eight; more decompositions exist.
