Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555408, here are decompositions:

11 + 33555397 = 33555408
17 + 33555391 = 33555408
31 + 33555377 = 33555408
67 + 33555341 = 33555408
127 + 33555281 = 33555408
137 + 33555271 = 33555408
149 + 33555259 = 33555408
157 + 33555251 = 33555408

Showing the first eight; more decompositions exist.
