Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533284, here are decompositions:

151 + 31533133 = 31533284
157 + 31533127 = 31533284
193 + 31533091 = 31533284
271 + 31533013 = 31533284
283 + 31533001 = 31533284
313 + 31532971 = 31533284
421 + 31532863 = 31533284
547 + 31532737 = 31533284

Showing the first eight; more decompositions exist.
