Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605778, here are decompositions:

29 + 33605749 = 33605778
61 + 33605717 = 33605778
109 + 33605669 = 33605778
131 + 33605647 = 33605778
211 + 33605567 = 33605778
337 + 33605441 = 33605778
359 + 33605419 = 33605778
389 + 33605389 = 33605778

Showing the first eight; more decompositions exist.
