Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557284, here are decompositions:

197 + 33557087 = 33557284
227 + 33557057 = 33557284
347 + 33556937 = 33557284
443 + 33556841 = 33557284
461 + 33556823 = 33557284
881 + 33556403 = 33557284
941 + 33556343 = 33557284
983 + 33556301 = 33557284

Showing the first eight; more decompositions exist.
