Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505866, here are decompositions:

7 + 33505859 = 33505866
13 + 33505853 = 33505866
19 + 33505847 = 33505866
67 + 33505799 = 33505866
89 + 33505777 = 33505866
293 + 33505573 = 33505866
347 + 33505519 = 33505866
367 + 33505499 = 33505866

Showing the first eight; more decompositions exist.
