Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520072, here are decompositions:

11 + 33520061 = 33520072
29 + 33520043 = 33520072
41 + 33520031 = 33520072
59 + 33520013 = 33520072
149 + 33519923 = 33520072
233 + 33519839 = 33520072
281 + 33519791 = 33520072
449 + 33519623 = 33520072

Showing the first eight; more decompositions exist.
