Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505320, here are decompositions:

11 + 33505309 = 33505320
19 + 33505301 = 33505320
59 + 33505261 = 33505320
67 + 33505253 = 33505320
73 + 33505247 = 33505320
109 + 33505211 = 33505320
157 + 33505163 = 33505320
197 + 33505123 = 33505320

Showing the first eight; more decompositions exist.
