Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533126, here are decompositions:

7 + 31533119 = 31533126
29 + 31533097 = 31533126
113 + 31533013 = 31533126
127 + 31532999 = 31533126
167 + 31532959 = 31533126
227 + 31532899 = 31533126
263 + 31532863 = 31533126
293 + 31532833 = 31533126

Showing the first eight; more decompositions exist.
