Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541520, here are decompositions:

7 + 33541513 = 33541520
13 + 33541507 = 33541520
31 + 33541489 = 33541520
37 + 33541483 = 33541520
43 + 33541477 = 33541520
157 + 33541363 = 33541520
211 + 33541309 = 33541520
223 + 33541297 = 33541520

Showing the first eight; more decompositions exist.
