Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511378, here are decompositions:

11 + 33511367 = 33511378
41 + 33511337 = 33511378
101 + 33511277 = 33511378
149 + 33511229 = 33511378
227 + 33511151 = 33511378
239 + 33511139 = 33511378
311 + 33511067 = 33511378
359 + 33511019 = 33511378

Showing the first eight; more decompositions exist.
