Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521406, here are decompositions:

5 + 33521401 = 33521406
13 + 33521393 = 33521406
227 + 33521179 = 33521406
229 + 33521177 = 33521406
307 + 33521099 = 33521406
349 + 33521057 = 33521406
367 + 33521039 = 33521406
397 + 33521009 = 33521406

Showing the first eight; more decompositions exist.
