Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557618, here are decompositions:

97 + 33557521 = 33557618
109 + 33557509 = 33557618
151 + 33557467 = 33557618
277 + 33557341 = 33557618
421 + 33557197 = 33557618
487 + 33557131 = 33557618
499 + 33557119 = 33557618
541 + 33557077 = 33557618

Showing the first eight; more decompositions exist.
