Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521256, here are decompositions:

19 + 33521237 = 33521256
37 + 33521219 = 33521256
79 + 33521177 = 33521256
157 + 33521099 = 33521256
173 + 33521083 = 33521256
199 + 33521057 = 33521256
269 + 33520987 = 33521256
277 + 33520979 = 33521256

Showing the first eight; more decompositions exist.
