Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557018, here are decompositions:

7 + 33557011 = 33557018
97 + 33556921 = 33557018
139 + 33556879 = 33557018
151 + 33556867 = 33557018
181 + 33556837 = 33557018
307 + 33556711 = 33557018
337 + 33556681 = 33557018
421 + 33556597 = 33557018

Showing the first eight; more decompositions exist.
