Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557320, here are decompositions:

3 + 33557317 = 33557320
233 + 33557087 = 33557320
257 + 33557063 = 33557320
263 + 33557057 = 33557320
311 + 33557009 = 33557320
359 + 33556961 = 33557320
383 + 33556937 = 33557320
431 + 33556889 = 33557320

Showing the first eight; more decompositions exist.
