Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605900, here are decompositions:

19 + 33605881 = 33605900
37 + 33605863 = 33605900
61 + 33605839 = 33605900
103 + 33605797 = 33605900
151 + 33605749 = 33605900
199 + 33605701 = 33605900
409 + 33605491 = 33605900
421 + 33605479 = 33605900

Showing the first eight; more decompositions exist.
