Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520428, here are decompositions:

31 + 33520397 = 33520428
59 + 33520369 = 33520428
61 + 33520367 = 33520428
107 + 33520321 = 33520428
157 + 33520271 = 33520428
197 + 33520231 = 33520428
281 + 33520147 = 33520428
367 + 33520061 = 33520428

Showing the first eight; more decompositions exist.
