Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533026, here are decompositions:

13 + 31533013 = 31533026
67 + 31532959 = 31533026
103 + 31532923 = 31533026
127 + 31532899 = 31533026
163 + 31532863 = 31533026
193 + 31532833 = 31533026
277 + 31532749 = 31533026
367 + 31532659 = 31533026

Showing the first eight; more decompositions exist.
