Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613280, here are decompositions:

3 + 33613277 = 33613280
7 + 33613273 = 33613280
37 + 33613243 = 33613280
67 + 33613213 = 33613280
109 + 33613171 = 33613280
199 + 33613081 = 33613280
241 + 33613039 = 33613280
271 + 33613009 = 33613280

Showing the first eight; more decompositions exist.
