Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505886, here are decompositions:

3 + 33505883 = 33505886
19 + 33505867 = 33505886
97 + 33505789 = 33505886
109 + 33505777 = 33505886
163 + 33505723 = 33505886
223 + 33505663 = 33505886
307 + 33505579 = 33505886
313 + 33505573 = 33505886

Showing the first eight; more decompositions exist.
