Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537400, here are decompositions:

3 + 33537397 = 33537400
11 + 33537389 = 33537400
41 + 33537359 = 33537400
107 + 33537293 = 33537400
137 + 33537263 = 33537400
167 + 33537233 = 33537400
173 + 33537227 = 33537400
227 + 33537173 = 33537400

Showing the first eight; more decompositions exist.
