Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505380, here are decompositions:

17 + 33505363 = 33505380
19 + 33505361 = 33505380
43 + 33505337 = 33505380
71 + 33505309 = 33505380
79 + 33505301 = 33505380
127 + 33505253 = 33505380
151 + 33505229 = 33505380
193 + 33505187 = 33505380

Showing the first eight; more decompositions exist.
