Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521660, here are decompositions:

13 + 33521647 = 33521660
31 + 33521629 = 33521660
37 + 33521623 = 33521660
199 + 33521461 = 33521660
223 + 33521437 = 33521660
229 + 33521431 = 33521660
439 + 33521221 = 33521660
577 + 33521083 = 33521660

Showing the first eight; more decompositions exist.
