Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557380, here are decompositions:

23 + 33557357 = 33557380
41 + 33557339 = 33557380
53 + 33557327 = 33557380
293 + 33557087 = 33557380
317 + 33557063 = 33557380
419 + 33556961 = 33557380
443 + 33556937 = 33557380
491 + 33556889 = 33557380

Showing the first eight; more decompositions exist.
