Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531280, here are decompositions:

11 + 33531269 = 33531280
47 + 33531233 = 33531280
113 + 33531167 = 33531280
197 + 33531083 = 33531280
269 + 33531011 = 33531280
281 + 33530999 = 33531280
311 + 33530969 = 33531280
443 + 33530837 = 33531280

Showing the first eight; more decompositions exist.
