Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621264, here are decompositions:

11 + 33621253 = 33621264
13 + 33621251 = 33621264
31 + 33621233 = 33621264
101 + 33621163 = 33621264
151 + 33621113 = 33621264
181 + 33621083 = 33621264
197 + 33621067 = 33621264
227 + 33621037 = 33621264

Showing the first eight; more decompositions exist.
