Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533170, here are decompositions:

3 + 31533167 = 31533170
37 + 31533133 = 31533170
43 + 31533127 = 31533170
73 + 31533097 = 31533170
79 + 31533091 = 31533170
157 + 31533013 = 31533170
199 + 31532971 = 31533170
211 + 31532959 = 31533170

Showing the first eight; more decompositions exist.
