Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557356, here are decompositions:

17 + 33557339 = 33557356
29 + 33557327 = 33557356
269 + 33557087 = 33557356
293 + 33557063 = 33557356
347 + 33557009 = 33557356
419 + 33556937 = 33557356
467 + 33556889 = 33557356
479 + 33556877 = 33557356

Showing the first eight; more decompositions exist.
