Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521436, here are decompositions:

5 + 33521431 = 33521436
19 + 33521417 = 33521436
43 + 33521393 = 33521436
199 + 33521237 = 33521436
257 + 33521179 = 33521436
337 + 33521099 = 33521436
349 + 33521087 = 33521436
353 + 33521083 = 33521436

Showing the first eight; more decompositions exist.
