Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533234, here are decompositions:

43 + 31533191 = 31533234
67 + 31533167 = 31533234
101 + 31533133 = 31533234
107 + 31533127 = 31533234
137 + 31533097 = 31533234
233 + 31533001 = 31533234
263 + 31532971 = 31533234
311 + 31532923 = 31533234

Showing the first eight; more decompositions exist.
