Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572388, here are decompositions:

7 + 33572381 = 33572388
11 + 33572377 = 33572388
37 + 33572351 = 33572388
41 + 33572347 = 33572388
79 + 33572309 = 33572388
137 + 33572251 = 33572388
151 + 33572237 = 33572388
197 + 33572191 = 33572388

Showing the first eight; more decompositions exist.
