Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513378, here are decompositions:

5 + 33513373 = 33513378
11 + 33513367 = 33513378
97 + 33513281 = 33513378
131 + 33513247 = 33513378
181 + 33513197 = 33513378
191 + 33513187 = 33513378
211 + 33513167 = 33513378
251 + 33513127 = 33513378

Showing the first eight; more decompositions exist.
