Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533236, here are decompositions:

103 + 31533133 = 31533236
109 + 31533127 = 31533236
139 + 31533097 = 31533236
223 + 31533013 = 31533236
277 + 31532959 = 31533236
313 + 31532923 = 31533236
337 + 31532899 = 31533236
373 + 31532863 = 31533236

Showing the first eight; more decompositions exist.
