Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556458, here are decompositions:

29 + 33556429 = 33556458
59 + 33556399 = 33556458
97 + 33556361 = 33556458
101 + 33556357 = 33556458
157 + 33556301 = 33556458
227 + 33556231 = 33556458
251 + 33556207 = 33556458
269 + 33556189 = 33556458

Showing the first eight; more decompositions exist.
