Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533254, here are decompositions:

127 + 31533127 = 31533254
157 + 31533097 = 31533254
163 + 31533091 = 31533254
241 + 31533013 = 31533254
283 + 31532971 = 31533254
331 + 31532923 = 31533254
373 + 31532881 = 31533254
421 + 31532833 = 31533254

Showing the first eight; more decompositions exist.
