Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33565872, here are decompositions:

19 + 33565853 = 33565872
31 + 33565841 = 33565872
59 + 33565813 = 33565872
61 + 33565811 = 33565872
113 + 33565759 = 33565872
139 + 33565733 = 33565872
163 + 33565709 = 33565872
181 + 33565691 = 33565872

Showing the first eight; more decompositions exist.
