Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545540, here are decompositions:

13 + 33545527 = 33545540
43 + 33545497 = 33545540
97 + 33545443 = 33545540
139 + 33545401 = 33545540
151 + 33545389 = 33545540
157 + 33545383 = 33545540
163 + 33545377 = 33545540
211 + 33545329 = 33545540

Showing the first eight; more decompositions exist.
