Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557518, here are decompositions:

47 + 33557471 = 33557518
89 + 33557429 = 33557518
101 + 33557417 = 33557518
107 + 33557411 = 33557518
131 + 33557387 = 33557518
179 + 33557339 = 33557518
191 + 33557327 = 33557518
431 + 33557087 = 33557518

Showing the first eight; more decompositions exist.
