Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521416, here are decompositions:

23 + 33521393 = 33521416
179 + 33521237 = 33521416
197 + 33521219 = 33521416
239 + 33521177 = 33521416
317 + 33521099 = 33521416
359 + 33521057 = 33521416
443 + 33520973 = 33521416
449 + 33520967 = 33521416

Showing the first eight; more decompositions exist.
