Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605660, here are decompositions:

13 + 33605647 = 33605660
181 + 33605479 = 33605660
241 + 33605419 = 33605660
271 + 33605389 = 33605660
367 + 33605293 = 33605660
397 + 33605263 = 33605660
409 + 33605251 = 33605660
433 + 33605227 = 33605660

Showing the first eight; more decompositions exist.
