Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533066, here are decompositions:

53 + 31533013 = 31533066
67 + 31532999 = 31533066
107 + 31532959 = 31533066
127 + 31532939 = 31533066
167 + 31532899 = 31533066
193 + 31532873 = 31533066
199 + 31532867 = 31533066
233 + 31532833 = 31533066

Showing the first eight; more decompositions exist.
