Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547280, here are decompositions:

3 + 33547277 = 33547280
37 + 33547243 = 33547280
127 + 33547153 = 33547280
163 + 33547117 = 33547280
199 + 33547081 = 33547280
223 + 33547057 = 33547280
229 + 33547051 = 33547280
307 + 33546973 = 33547280

Showing the first eight; more decompositions exist.
