Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613428, here are decompositions:

41 + 33613387 = 33613428
61 + 33613367 = 33613428
89 + 33613339 = 33613428
151 + 33613277 = 33613428
157 + 33613271 = 33613428
181 + 33613247 = 33613428
197 + 33613231 = 33613428
241 + 33613187 = 33613428

Showing the first eight; more decompositions exist.
