Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521290, here are decompositions:

53 + 33521237 = 33521290
71 + 33521219 = 33521290
113 + 33521177 = 33521290
149 + 33521141 = 33521290
191 + 33521099 = 33521290
233 + 33521057 = 33521290
251 + 33521039 = 33521290
269 + 33521021 = 33521290

Showing the first eight; more decompositions exist.
