Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520172, here are decompositions:

3 + 33520169 = 33520172
43 + 33520129 = 33520172
109 + 33520063 = 33520172
193 + 33519979 = 33520172
223 + 33519949 = 33520172
229 + 33519943 = 33520172
379 + 33519793 = 33520172
421 + 33519751 = 33520172

Showing the first eight; more decompositions exist.
