Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521620, here are decompositions:

71 + 33521549 = 33521620
89 + 33521531 = 33521620
137 + 33521483 = 33521620
149 + 33521471 = 33521620
227 + 33521393 = 33521620
383 + 33521237 = 33521620
401 + 33521219 = 33521620
443 + 33521177 = 33521620

Showing the first eight; more decompositions exist.
