Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521680, here are decompositions:

131 + 33521549 = 33521680
149 + 33521531 = 33521680
197 + 33521483 = 33521680
263 + 33521417 = 33521680
359 + 33521321 = 33521680
443 + 33521237 = 33521680
461 + 33521219 = 33521680
503 + 33521177 = 33521680

Showing the first eight; more decompositions exist.
