Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557660, here are decompositions:

43 + 33557617 = 33557660
139 + 33557521 = 33557660
151 + 33557509 = 33557660
193 + 33557467 = 33557660
337 + 33557323 = 33557660
457 + 33557203 = 33557660
463 + 33557197 = 33557660
541 + 33557119 = 33557660

Showing the first eight; more decompositions exist.
