Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545550, here are decompositions:

23 + 33545527 = 33545550
53 + 33545497 = 33545550
67 + 33545483 = 33545550
107 + 33545443 = 33545550
127 + 33545423 = 33545550
149 + 33545401 = 33545550
167 + 33545383 = 33545550
173 + 33545377 = 33545550

Showing the first eight; more decompositions exist.
