Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557020, here are decompositions:

11 + 33557009 = 33557020
59 + 33556961 = 33557020
83 + 33556937 = 33557020
131 + 33556889 = 33557020
173 + 33556847 = 33557020
179 + 33556841 = 33557020
197 + 33556823 = 33557020
251 + 33556769 = 33557020

Showing the first eight; more decompositions exist.
