Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533084, here are decompositions:

71 + 31533013 = 31533084
83 + 31533001 = 31533084
103 + 31532981 = 31533084
113 + 31532971 = 31533084
211 + 31532873 = 31533084
251 + 31532833 = 31533084
307 + 31532777 = 31533084
347 + 31532737 = 31533084

Showing the first eight; more decompositions exist.
