Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557420, here are decompositions:

3 + 33557417 = 33557420
7 + 33557413 = 33557420
79 + 33557341 = 33557420
97 + 33557323 = 33557420
103 + 33557317 = 33557420
163 + 33557257 = 33557420
223 + 33557197 = 33557420
277 + 33557143 = 33557420

Showing the first eight; more decompositions exist.
