Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545220, here are decompositions:

13 + 33545207 = 33545220
29 + 33545191 = 33545220
31 + 33545189 = 33545220
43 + 33545177 = 33545220
47 + 33545173 = 33545220
53 + 33545167 = 33545220
73 + 33545147 = 33545220
101 + 33545119 = 33545220

Showing the first eight; more decompositions exist.
