Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521172, here are decompositions:

31 + 33521141 = 33521172
73 + 33521099 = 33521172
89 + 33521083 = 33521172
151 + 33521021 = 33521172
163 + 33521009 = 33521172
193 + 33520979 = 33521172
199 + 33520973 = 33521172
233 + 33520939 = 33521172

Showing the first eight; more decompositions exist.
