Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605990, here are decompositions:

31 + 33605959 = 33605990
109 + 33605881 = 33605990
127 + 33605863 = 33605990
151 + 33605839 = 33605990
193 + 33605797 = 33605990
241 + 33605749 = 33605990
277 + 33605713 = 33605990
307 + 33605683 = 33605990

Showing the first eight; more decompositions exist.
