Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557388, here are decompositions:

31 + 33557357 = 33557388
47 + 33557341 = 33557388
61 + 33557327 = 33557388
71 + 33557317 = 33557388
131 + 33557257 = 33557388
191 + 33557197 = 33557388
257 + 33557131 = 33557388
269 + 33557119 = 33557388

Showing the first eight; more decompositions exist.
