Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547428, here are decompositions:

7 + 33547421 = 33547428
11 + 33547417 = 33547428
41 + 33547387 = 33547428
107 + 33547321 = 33547428
137 + 33547291 = 33547428
151 + 33547277 = 33547428
281 + 33547147 = 33547428
311 + 33547117 = 33547428

Showing the first eight; more decompositions exist.
