Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520016, here are decompositions:

3 + 33520013 = 33520016
37 + 33519979 = 33520016
67 + 33519949 = 33520016
73 + 33519943 = 33520016
109 + 33519907 = 33520016
139 + 33519877 = 33520016
223 + 33519793 = 33520016
307 + 33519709 = 33520016

Showing the first eight; more decompositions exist.
