Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521638, here are decompositions:

89 + 33521549 = 33521638
107 + 33521531 = 33521638
167 + 33521471 = 33521638
317 + 33521321 = 33521638
401 + 33521237 = 33521638
419 + 33521219 = 33521638
461 + 33521177 = 33521638
467 + 33521171 = 33521638

Showing the first eight; more decompositions exist.
