Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525220, here are decompositions:

11 + 33525209 = 33525220
23 + 33525197 = 33525220
83 + 33525137 = 33525220
257 + 33524963 = 33525220
269 + 33524951 = 33525220
293 + 33524927 = 33525220
389 + 33524831 = 33525220
401 + 33524819 = 33525220

Showing the first eight; more decompositions exist.
