Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605720, here are decompositions:

3 + 33605717 = 33605720
7 + 33605713 = 33605720
19 + 33605701 = 33605720
37 + 33605683 = 33605720
73 + 33605647 = 33605720
229 + 33605491 = 33605720
241 + 33605479 = 33605720
277 + 33605443 = 33605720

Showing the first eight; more decompositions exist.
