Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533032, here are decompositions:

19 + 31533013 = 31533032
31 + 31533001 = 31533032
61 + 31532971 = 31533032
73 + 31532959 = 31533032
109 + 31532923 = 31533032
151 + 31532881 = 31533032
199 + 31532833 = 31533032
283 + 31532749 = 31533032

Showing the first eight; more decompositions exist.
