Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605640, here are decompositions:

73 + 33605567 = 33605640
97 + 33605543 = 33605640
109 + 33605531 = 33605640
149 + 33605491 = 33605640
197 + 33605443 = 33605640
199 + 33605441 = 33605640
223 + 33605417 = 33605640
251 + 33605389 = 33605640

Showing the first eight; more decompositions exist.
