Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533006, here are decompositions:

5 + 31533001 = 31533006
7 + 31532999 = 31533006
47 + 31532959 = 31533006
67 + 31532939 = 31533006
83 + 31532923 = 31533006
107 + 31532899 = 31533006
139 + 31532867 = 31533006
173 + 31532833 = 31533006

Showing the first eight; more decompositions exist.
