Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545660, here are decompositions:

3 + 33545657 = 33545660
37 + 33545623 = 33545660
61 + 33545599 = 33545660
103 + 33545557 = 33545660
163 + 33545497 = 33545660
271 + 33545389 = 33545660
277 + 33545383 = 33545660
283 + 33545377 = 33545660

Showing the first eight; more decompositions exist.
