Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506172, here are decompositions:

19 + 33506153 = 33506172
41 + 33506131 = 33506172
59 + 33506113 = 33506172
61 + 33506111 = 33506172
79 + 33506093 = 33506172
179 + 33505993 = 33506172
191 + 33505981 = 33506172
211 + 33505961 = 33506172

Showing the first eight; more decompositions exist.
