Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621340, here are decompositions:

29 + 33621311 = 33621340
41 + 33621299 = 33621340
89 + 33621251 = 33621340
107 + 33621233 = 33621340
167 + 33621173 = 33621340
191 + 33621149 = 33621340
227 + 33621113 = 33621340
257 + 33621083 = 33621340

Showing the first eight; more decompositions exist.
