Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609942, here are decompositions:

11 + 33609931 = 33609942
29 + 33609913 = 33609942
43 + 33609899 = 33609942
173 + 33609769 = 33609942
181 + 33609761 = 33609942
193 + 33609749 = 33609942
199 + 33609743 = 33609942
241 + 33609701 = 33609942

Showing the first eight; more decompositions exist.
