Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605888, here are decompositions:

7 + 33605881 = 33605888
139 + 33605749 = 33605888
241 + 33605647 = 33605888
397 + 33605491 = 33605888
409 + 33605479 = 33605888
499 + 33605389 = 33605888
619 + 33605269 = 33605888
661 + 33605227 = 33605888

Showing the first eight; more decompositions exist.
