Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521320, here are decompositions:

83 + 33521237 = 33521320
101 + 33521219 = 33521320
149 + 33521171 = 33521320
179 + 33521141 = 33521320
233 + 33521087 = 33521320
263 + 33521057 = 33521320
281 + 33521039 = 33521320
311 + 33521009 = 33521320

Showing the first eight; more decompositions exist.
