Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520818, here are decompositions:

5 + 33520813 = 33520818
17 + 33520801 = 33520818
41 + 33520777 = 33520818
59 + 33520759 = 33520818
109 + 33520709 = 33520818
131 + 33520687 = 33520818
137 + 33520681 = 33520818
151 + 33520667 = 33520818

Showing the first eight; more decompositions exist.
