Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521666, here are decompositions:

19 + 33521647 = 33521666
37 + 33521629 = 33521666
43 + 33521623 = 33521666
127 + 33521539 = 33521666
229 + 33521437 = 33521666
487 + 33521179 = 33521666
727 + 33520939 = 33521666
823 + 33520843 = 33521666

Showing the first eight; more decompositions exist.
