Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533272, here are decompositions:

3 + 31533269 = 31533272
13 + 31533259 = 31533272
139 + 31533133 = 31533272
181 + 31533091 = 31533272
271 + 31533001 = 31533272
313 + 31532959 = 31533272
349 + 31532923 = 31533272
373 + 31532899 = 31533272

Showing the first eight; more decompositions exist.
