Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581532, here are decompositions:

11 + 33581521 = 33581532
41 + 33581491 = 33581532
139 + 33581393 = 33581532
151 + 33581381 = 33581532
181 + 33581351 = 33581532
211 + 33581321 = 33581532
233 + 33581299 = 33581532
241 + 33581291 = 33581532

Showing the first eight; more decompositions exist.
