Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511408, here are decompositions:

11 + 33511397 = 33511408
41 + 33511367 = 33511408
71 + 33511337 = 33511408
131 + 33511277 = 33511408
179 + 33511229 = 33511408
251 + 33511157 = 33511408
257 + 33511151 = 33511408
269 + 33511139 = 33511408

Showing the first eight; more decompositions exist.
