Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557438, here are decompositions:

97 + 33557341 = 33557438
181 + 33557257 = 33557438
241 + 33557197 = 33557438
307 + 33557131 = 33557438
337 + 33557101 = 33557438
571 + 33556867 = 33557438
601 + 33556837 = 33557438
727 + 33556711 = 33557438

Showing the first eight; more decompositions exist.
