Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521178, here are decompositions:

7 + 33521171 = 33521178
37 + 33521141 = 33521178
79 + 33521099 = 33521178
139 + 33521039 = 33521178
157 + 33521021 = 33521178
191 + 33520987 = 33521178
199 + 33520979 = 33521178
211 + 33520967 = 33521178

Showing the first eight; more decompositions exist.
