Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533036, here are decompositions:

23 + 31533013 = 31533036
37 + 31532999 = 31533036
97 + 31532939 = 31533036
113 + 31532923 = 31533036
137 + 31532899 = 31533036
163 + 31532873 = 31533036
173 + 31532863 = 31533036
349 + 31532687 = 31533036

Showing the first eight; more decompositions exist.
