Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520440, here are decompositions:

11 + 33520429 = 33520440
43 + 33520397 = 33520440
67 + 33520373 = 33520440
71 + 33520369 = 33520440
73 + 33520367 = 33520440
137 + 33520303 = 33520440
157 + 33520283 = 33520440
167 + 33520273 = 33520440

Showing the first eight; more decompositions exist.
