Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521148, here are decompositions:

7 + 33521141 = 33521148
61 + 33521087 = 33521148
109 + 33521039 = 33521148
127 + 33521021 = 33521148
139 + 33521009 = 33521148
181 + 33520967 = 33521148
229 + 33520919 = 33521148
257 + 33520891 = 33521148

Showing the first eight; more decompositions exist.
