Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533134, here are decompositions:

7 + 31533127 = 31533134
37 + 31533097 = 31533134
43 + 31533091 = 31533134
163 + 31532971 = 31533134
211 + 31532923 = 31533134
271 + 31532863 = 31533134
397 + 31532737 = 31533134
541 + 31532593 = 31533134

Showing the first eight; more decompositions exist.
