Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520018, here are decompositions:

5 + 33520013 = 33520018
89 + 33519929 = 33520018
179 + 33519839 = 33520018
227 + 33519791 = 33520018
269 + 33519749 = 33520018
359 + 33519659 = 33520018
401 + 33519617 = 33520018
479 + 33519539 = 33520018

Showing the first eight; more decompositions exist.
