Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533212, here are decompositions:

3 + 31533209 = 31533212
79 + 31533133 = 31533212
199 + 31533013 = 31533212
211 + 31533001 = 31533212
241 + 31532971 = 31533212
313 + 31532899 = 31533212
331 + 31532881 = 31533212
349 + 31532863 = 31533212

Showing the first eight; more decompositions exist.
